Shiga Toxin‒Producing Escherichia coli Diagnoses from Health Practitioners, Queensland, Australia.

In Queensland, Australia, 31 of 96 Shiga toxin‒producing Escherichia coli cases during 2020-2022 were reported by a specialty pathology laboratory servicing alternative health practitioners. Those new cases were more likely to be asymptomatic or paucisymptomatic, prompting a review of the standard public health response.

Integrating Veterinary Diagnostic Laboratories for Emergency Use Testing during Pandemics1.

The SARS-CoV-2 pandemic showed limitations in human outbreak testing. Veterinary diagnostic laboratories (VDLs) possess capabilities to bolster emergency test capacity. Surveys from 26 participating VDLs found human SARS-CoV-2 testing was mutually beneficial, including One Health benefits. VDLs indicated testing >3.8 million human samples during the pandemic, which included some challenges.

Is drug interference still an issue for pretransfusion testing of patients on anti CD38 and other monoclonal antibody therapies?

Certain therapies that target CD markers on some blood cells can affect pretransfusion testing. Key examples are anti-CD38, CD47 monoclonal antibody (mAb) therapies such as daratumumab (DARA) and magrolimab, which have presented a challenge for transfusion medicine laboratories around the globe. Scientists have been faced with not only introducing a protocol to provide safe blood to patients but also investigating the most effective method to remove the pretransfusion pan-agglutinating interference caused. A number of papers in the last 5 years have reported on various methods to remove pretransfusion interference; however, most of these studies have been conducted only in a few countries. Most recent reviews on this topic have focused on techniques and reagents to remove pretransfusion interference, and dithiothreitol is currently the gold standard for removing DARA interference. However, it was clear from this review that while many laboratories have developed processes for addressing interference in pretransfusion testing, and DARA interference may not be a major issue, there are still laboratories around the world, that may not have adequately addressed this issue. In addition, the impact of mAb interference on widely used techniques such as flow cytometry is unclear.

Issues in assessing analytical performance specifications in healthcare systems assembling multiple laboratories and measuring systems.

Analytical performance specifications (APS) are usually compared to the intermediate reproducibility uncertainty of measuring a particular measurand using a single in vitro diagnostic medical device (IVD MD). Healthcare systems assembling multiple laboratories that include several IVD MDs and cater to patients suffering from long-term disease conditions mean that samples from a patient are analyzed using a few IVD MDs, sometimes from different manufacturers, but rarely all IVD MDs in the healthcare system. The reproducibility uncertainty for results of a measurand measured within a healthcare system and the components of this measurement uncertainty is useful in strategies to minimize bias and overall measurement uncertainty within the healthcare system. The root mean squares deviation (RMSD) calculated as the sample standard deviation (SD) and relative SD includes both imprecision and bias and is appropriate for expressing such uncertainties. Results from commutable stabilized internal and external control samples, from measuring split natural patient samples or using big-data techniques, are essential in monitoring bias and measurement uncertainties in healthcare systems. Variance component analysis (VCA) can be employed to quantify the relative contributions of the most influential factors causing measurement uncertainty. Such results represent invaluable information for minimizing measurement uncertainty in the interest of the healthcare system's patients.

Organisation of paediatric echocardiography laboratories and governance of echocardiography services and training in Europe: current status, disparities, and potential solutions. A survey from the Association for European Paediatric and Congenital Cardiology (AEPC) imaging working group.

BACKGROUND: There is limited data on the organisation of paediatric echocardiography laboratories in Europe. METHODS: A structured and approved questionnaire was circulated across all 95 Association for European Paediatric and Congenital Cardiology affiliated centres. The aims were to evaluate: (1) facilities in paediatric echocardiography laboratories across Europe, (2) accredited laboratories, (3) medical/paramedical staff employed, (4) time for echocardiographic studies and reporting, and (5) training, teaching, quality improvement, and research programs. RESULTS: Respondents from forty-three centres (45%) in 22 countries completed the survey. Thirty-six centres (84%) have a dedicated paediatric echocardiography laboratory, only five (12%) of which reported they were European Association of Cardiovascular Imaging accredited. The median number of echocardiography rooms was three (range 1-12), and echocardiography machines was four (range 1-12). Only half of all the centres have dedicated imaging physiologists and/or nursing staff, while the majority (79%) have specialist imaging cardiologist(s). The median (range) duration of time for a new examination was 45 (20-60) minutes, and for repeat examination was 20 (5-30) minutes. More than half of respondents (58%) have dedicated time for reporting. An organised training program was present in most centres (78%), 44% undertake quality assurance, and 79% perform research. Guidelines for performing echocardiography were available in 32 centres (74%). CONCLUSION: Facilities, staffing levels, study times, standards in teaching/training, and quality assurance vary widely across paediatric echocardiography laboratories in Europe. Greater support and investment to facilitate improvements in staffing levels, equipment, and governance would potentially improve European paediatric echocardiography laboratories.

Can video-assisted and three-dimensional (3D) anatomy teaching be an alternative to traditional anatomy teaching? Randomized controlled trial on muscular system anatomy.

The aim of this study was to determine the optimal method for teaching human anatomy by comparing classical laboratory (traditional), video-assisted and three-dimensional (3D) application methods for students who had previously received only online academic anatomy education. GPower 3.1.9.4 was used for power analysis to establish sample size. After power analysis, it was decided to have 28 people in each group. Participants were given pre-anatomy education tests and divided into four matched groups: Group 1: no additional education, Group 2: Video-assisted education, Group 3: Applied 3D anatomy education, Group 4: Practical laboratory anatomy education. Each group received 5 weeks of education in muscular system anatomy. The pre-test results showed no statistically significant differences among the groups. The post-test results showed statistically significant improvement in scores (p < 0.001): group 4; 59%, group 3; 33%, group 2; 9%. The difference between group 1 and group 2 was statistically significant (p < 0.01). The difference between the groups in post hoc comparisons with all other groups was also statistically significant (p < 0.001). The results of this study show that while the optimal anatomy teaching method is conservative, the best alternative is 3D application.

[Benefits and approaches of a quality management system in biomedical research laboratories]. / Vorteile und Ansätze eines Qualitätsmanagementsystems in biomedizinischen Forschungslaboratorien.

Quality in biomedical research is a much-discussed topic among experts, research institutes, and funding organizations. Quality issues are frequently reported in the scientific and general press (e.g., stability of study results after test retake - "replication crisis"). Quality management systems are a globally accepted and established tool to guide and manage quality and to address quality problems. However, the notion of quality management is often met with resistance among researchers: low resources, too much regulation, restriction of research, and unnecessary bureaucracy are counter-arguments.The idea of implementing a quality management system for research laboratories is nothing new worldwide. There are various approaches by scientists and organizations to establish a quality management system in research laboratories and to develop a value-added system for themselves. Their expectations are an optimization of the research processes as well as an increase in effectiveness and efficiency.This report summarizes publications concerning quality measures and management in biomedical research and explains the background and advantages of quality management systems in organizations, laboratories, and research. A currently ongoing project of the Robert Koch Institute is presented as an outlook. The article is based on a literature review in English and German. In addition, internationally and nationally applicable and relevant guidelines were considered.

[Proceedings of the International Symposium of the World Association of Veterinary Laboratory Diagnosticians, 2023]. / Compte-rendu du Symposium international de la Société mondiale des Laboratoires vétérinaires de diagnostic, 2023.

The International Symposium of the World Association of Veterinary Laboratory Diagnosticians (ISWAVLD) is the unmissable biannual meeting of all diagnostic veterinary laboratories including biologists, veterinarians and other scientists involved in laboratory diagnostics. It took place at the Lyon Convention Centre (29 June-1 July 2023). It was a pleasant and enriching moment, which allowed participants to discover and/or discuss new diagnostic methods and the epidemiology of animal diseases, around all themes involving veterinarians (animal health, but also environmental and human health, and food safety).

The experience and reflections of GC labs as an independent clinical laboratory to the COVID-19 pandemic in South Korea.

BACKGROUND: Amid the COVID-19 pandemic, extensive testing was undertaken by independent clinical laboratories (ICLs), yet limited research exists on this matter. Drawing from Green Cross Laboratories (GC Labs)' pandemic response experience, this study seeks to offer insights for preparation for the next pandemic. METHODS: This retrospective study analyzed the outcomes of SARS-CoV-2 real-time reverse transcription polymerase chain reaction (SARS-CoV-2 rRT PCR) tests administered by GC Labs for COVID-19 diagnosis, upon request by different organizations, between February 2020 and April 2022. The distribution of institutions that requested the tests, the type of tests, and the positive rate were analyzed. We investigated resource allocation details. RESULTS: ICLs were responsible for conducting 85.6% of all tests carried out under South Korea's COVID-19 testing policy during the pandemic. The availability of free testing regardless of symptoms led to a significant increase in the use of pooled tests, which accounted for more than 80% of all tests conducted after August 2021. The gender and age distribution of COVID-19 cases nationwide and GC Labs' positive cases were similar. When we analyzed the positive rate by requesting organizations during the COVID-19 pandemic, despite an overall nationwide positivity rate of 35%, high-risk facilities exhibited a positivity rate of less than 5% by maintaining preemptive testing. The most notable increase in resources during the pandemic was seen in human resource input. CONCLUSIONS: South Korea's ICLs were able to conduct large volumes of testing during the COVID-19 pandemic because of their logistics and computer systems, scalable testing space, and trained testing personnel. They also had the flexibility to bring in additional resources to expand testing capacity because they are specialized testing organizations. Hence, ICLs could execute the pooled test that the government had introduced for extensive general population screening. The preemptive periodic testing of high-risk populations kept the positive rate much lower than in the general population. This study's findings will aid in refining mass testing-based policies for the next pandemic.

Embedding education into clinical laboratory professional training to foster sustainable development and greener practice.

It has become apparent that the climate crisis is reaching critical levels and Governments and key organisations are recognising the need for change. A review of current literature reveals very little published research concerning the impact of clinical laboratory practice on the carbon footprint of healthcare. For a clinical laboratory to become more environmentally sound, key target areas of focus are required. With sustainability becoming a key consideration for course development, employing educational principles such as Education for Sustainable Development (ESD) in the form of Sustainability in Quality Improvement (SusQI), Quality Improvement objectives can be met, while benefitting the patient and the environmental impact of organisation.

External quality assessment practices in medical laboratories: an IFCC global survey of member societies.

OBJECTIVES: Clinical laboratory results are required for critical medical decisions, underscoring the importance of quality results. As part of total quality management, external quality assessment (EQA) is a vital component to ensure laboratory accuracy. The goal of this survey was to evaluate the current status of global laboratory quality systems and assess the need for implementation, expansion, or harmonization of EQA programs (EQAP) for Clinical Chemistry and Laboratory Medicine. METHODS: The International Federation of Clinical Chemistry and Laboratory Medicine (IFCC) Task Force on Global Laboratory Quality (TF-GLQ) conducted a survey of IFCC full and affiliate members (n=110) on laboratory quality practice. A total of 41 (37.3%) countries representing all IFCC regions except North America provided responses about EQA availability and practices. RESULTS: All 41 countries perform EQA, 38 reported that their laboratories had EQA policies and procedures, and 39 further act/evaluate unacceptable EQA results. 39 countries indicated they have international and/or national EQAP and 30 use alternative performance assessments. EQA frequency varied among countries. Generally, an EQAP provided the EQA materials (40/41) with four countries indicating that they did not have an EQAP in their country. CONCLUSIONS: Globally, most laboratories participate in an EQAP and have defined quality procedures for EQA. There remain gaps in EQA material availability and implementation of EQA as a part of a total laboratory quality system. This survey highlights the need for education, training, and harmonization and will guide efforts of the IFCC TF-GLQ in identifying areas for enhancing global laboratory quality practices.

Quality standards and internal quality control practices in medical laboratories: an IFCC global survey of member societies.

OBJECTIVES: The trueness and precision of clinical laboratory results are ensured through total quality management systems (TQM), which primarily include internal quality control (IQC) practices. However, quality practices vary globally. To understand the current global state of IQC practice and IQC management in relation to TQM the International Federation of Clinical Chemistry and Laboratory Medicine (IFCC) Task Force on Global Laboratory Quality (TF-GLQ) conducted a survey of IFCC member countries on IQC practices and management. METHODS: The survey included 16 questions regarding IQC and laboratory TQM practices and was distributed to IFCC full and affiliate member countries (n=110). A total of 46 (41.8 %) responses were received from all regions except North America. RESULTS: Of the responding countries, 78.3 % (n=36) had legislative regulations or accreditation requirements governing medical laboratory quality standards. However, implementation was not mandatory in 46.7 % (n=21) of responding countries. IQC practices varied considerably with 57.1 % (n=28) of respondents indicating that they run 2 levels of IQC, 66.7 % (n=24) indicating they run IQC every 24 h and 66.7 % (n=28) using assay manufacturer IQC material sources. Only 29.3 % (n=12) of respondents indicated that every medical laboratory in their country has written IQC policies and procedures. By contrast, 97.6 % (n=40) of responding countries indicated they take corrective action and result remediation in the event of IQC failure. CONCLUSIONS: The variability in TQM and IQC practices highlights the need for more formal programs and education to standardize and improve TQM in medical laboratories.

Technical and health governance aspects of the External Quality Assessment Scheme for the SARS-CoV-2 molecular tests: institutional experience performed in all clinical laboratories of a Regional Health Service.

OBJECTIVES: Since December 2019, the worldwide public health has been threatened by a severe acute respiratory syndrome caused by Coronavirus-2. From the beginning, a turning point has been the identification of new cases of infection, in order to minimize the virus spreading among the population. For this reason, it was necessary introducing a panel of tests able to identify positive cases, which became crucial for all countries. METHODS: As a Regional Reference Centre, the CRQ Laboratory (Regional Laboratory for the Quality Control) developed and conducted an External Quality Assessment (EQA) panel of assay, so as to evaluate the quality of real-time reverse transcription polymerase chain reaction (PCR), which were used by 62 Sicilian laboratories, previously authorized to issue certificates for the COVID-19 diagnosis, on behalf of the Public Health Service. RESULTS: The qualitative performance test was based on pooled samples with different viral loads of SARS-CoV-2 or human Coronavirus OC43. 75% of the participating laboratories tested all core samples correctly, while the remaining 25% interpreted incorrectly the EQA exercise samples matching negatively the standards required. CONCLUSIONS: Subsequent inspection visits confirmed the issue of incorrect positive and negative certifications for COVID-19 by private and public laboratories, despite the possession of the authorization requirements currently provided for by current regulations, with a significant impact on the SSR.

Integrating 3Rs approaches in WHO guidelines for the batch release testing of biologicals: Responses from a survey of National Control Laboratories and National Regulatory Authorities.

The UK National Centre for the Replacement, Refinement, and Reduction of Animals in Research (NC3Rs) is reviewing World Health Organization (WHO) manuals, guidelines and recommendations for vaccines and biotherapeutics to identify the extent to which animal-based testing methods are described. The aim is to recommend where updates to these documents can lead to an increased and more harmonised adoption of 3Rs principles (i.e. Replacement, Reduction and Refinement of animal tests) in the quality control and batch release testing requirements for vaccines and biotherapeutics. Improved adoption of 3Rs principles and non-animal testing strategies will help to reduce the delays and costs associated with product release testing. Developing recommendations that are widely applicable by both the manufacturers and national regulatory authorities for vaccines and biological therapeutics globally requires a detailed understanding of how different organisations view the opportunities and barriers to better integration of the 3Rs. To facilitate this, we developed and distributed a survey aimed at individuals who work for national regulatory authorities (NRAs) and/or national control laboratories (NCLs). In this paper, we present the key findings from this survey and how these will help inform the recommendations for wider integration of 3Rs approaches by WHO in their guidance documents applicable to the quality control and batch release testing of vaccines and biotherapeutics.

Clinicians' satisfaction with laboratory services and associated factors at public health facilities in Northeast Ethiopia.

BACKGROUND: Satisfaction has become a key measure of quality and an important tool for improvement. Laboratories are increasingly required to regularly assess satisfaction of their customers. This study aimed to assess clinicians' satisfaction with laboratory services and associated factors at public health facilities. METHODS: A facility-based cross-sectional study was conducted in Northeast Ethiopia from May to June 2019. Eight hospitals and 24 health centres were first selected using a stratified sampling method, and a total of 224 randomly selected clinicians were included. Satisfaction with multiple aspects of laboratory services was assessed using a self-administered questionnaire, on a rating scale of 1 (very dissatisfied) to 5 points (very satisfied). Laboratory quality assessment was performed using WHO-AFRO's stepwise accreditation checklist. Multivariable logistic regression model was fitted to determine the association between independent variables and clinicians' overall satisfaction level using STATA ver14.1. A p-value < 0.05 was considered significant. RESULTS: Overall, 72.8% of the clinicians were satisfied. Lowest mean ratings were obtained for the helpfulness of the laboratory handbook (3.3), provision of STAT/urgent services (3.7), and adequacy of tests provided (3.8). The clinicians' timely receipt of results (AOR = 2.3, 95% CI = 1.1-5.0), notification of panic results (AOR = 2.5, 95% CI = 1.1-5.6), perceived quality/reliability of test results (AOR = 3.1, 95% CI = 1.5-6.3), and the laboratories' rate of concordant malaria microscopy results (AOR = 4.1, 95% CI = 1.8-9.3), were significantly associated with satisfaction. CONCLUSIONS: Nearly one-third of clinicians were not satisfied with the laboratory services. Laboratory managers should emphasize the timely communication of STAT/urgent and panic results, and the reliability of test results, to improve users' satisfaction and overall quality of care.

Qualitative Bioinformatics: Towards a Public Understanding of Neurodegenerative Disease Research through BioArt, Data-Art, Hands-on BioMedia Workshops, Immersive Environments, and Artists in Labs.

Neurodegenerative disease (ND) research is producing new pharmaceutical compounds for chronic diseases utilizing bioinformatics. Algorithmic data mining of high-throughput omics systems is conjoined with the study of the in vitro dynamics of protein folding through visualization techniques, i.e., Bio-AFM. Novel models of disease pathway diagrams are being produced and the processes are in place to enhance the validation of these models. From bench work to BLAST to bedside, globally standardized research is led by collaborative clusters, working on cloud-based platforms, with crowd sourced human cohort collections, pairing pure, curiosity-based neurological research with deep learning data analysis techniques. ND research is leading the way towards clinical applications for preventing, curing, or ameliorating major diseases of neurological dysfunction, such as Alzheimer's disease (AD) and Parkinson's disease (PD).Most of this is too complex for the average citizen to comprehend. Can bioart and data-art contribute to the public understanding of genome sequencing and bioinformatics databases in the context of ND research? Informal studies towards demystifying bioinformatics through creative practices have been tested, revealing significant qualitative benefits for public well-being while introducing bioinformatics databases, for instance, previous projects: the VASTAL Bioinformatics and Literary Studies: (De)Mystified Genetic Code Lab, held at the Waag in Amsterdam, NL, 2009 and more recently the Creative Germline Constructs Bank (CGCB) of the transgenic human Genome Alternatives Project (thGAP), held at Hackteria ZET, Zurich, Switzerland, 2021.For the Hub of Art Laboratories (HAL), of the Department of Audio & Visual Arts (AVArts), Ionian University in Corfu, Greece, the animation node is challenged to create audiovisual, immersive, and interactive environments that highlight natural processes and phenomena of the microcosm and macrocosm through nature/data interface experimentation. It is the intention of the node's researchers to expand these notions to be inclusive of the processes of the biotechnological and bioinformatics interrogation of human disease as a part of local clades and global nature. In our productions, we would like to emphasize: cryogenic storage, genome analysis, bioinformatic database management, biomarkers for polygenic abnormalities, genotyping/phenotyping, gene expression patterns over time, AI reading of cloud-based research, experiencial DNA/RNA synthesis, the development of novel DNA, RNA and protein-based therapeutic agents for biomedical applications and CRISPR construct design for model organisms. It is the HAL animation node's goal to design and explore bioart-based, hands-on public workshops that mix bioinformatics and data-art with in-depth knowledge of the scientific community around ND research bodies.To develop these labs, dedicated artistic research is required to be undertaken through laboratory immersion, interactions with scientists, and hands-on experience in the lab. Artists must experience scientific processes through residencies in labs to learn both how to convey the techniques and the social implications of novel methodologies. Artists developing bioart workshops that can introduce non-specialists to a dizzying array of research methodologies need to know what they are talking about. It takes experience and dedication to convey simplified versions of real-time biosensor data, automated histology, clinical databases of medical case studies (anonymized clients), real-time PCR, novel diagnostic biomarker development, etc. As qualitative researchers, artists in labs ensure creative yet informed art and science (SciArt) outcomes able to stimulate public debate through unorthodox education and accurate playfulness. Obviously, the immersive experience of lab research provides an artist's projects with both nuance and knowledge. How can artists in labs also add to the scientific potentials of a laboratory's research goals?

Creation of 21st century anatomy facilities: designing facilities for integrated preclinical education in the Middle East.

BACKGROUND: The establishment of new anatomy facilities needs to accommodate a combination of modern teaching modalities that best align with evidence-based best teaching practices. This article describes the process in which our state-of-the-art anatomy laboratories were designed and implemented, and how these facilities support aspects of modern anatomy education. METHODS: A list of best practices for anatomy education in a modern medical curriculum was summarized from the literature. To assess student satisfaction, a survey related to student perception of the anatomy facilities (5-point Likert scale) was conducted. RESULTS: Our educational modalities include a broad range of teaching approaches. The Instructional Studio houses prosected and plastinated specimens, and cadaveric dissections are performed. Each of our three Dry Laboratories allow for active learning and interaction between small student groups. The Webinar Room acts as a conference room for departmental and online meetings, discussions with students, and dialogues with affiliated hospitals via the internet. The Imaging Center is equipped with a Sectra® medical educational platform, CAE Vimedix® Virtual Medical Imaging Ultrasound Training System, and Philipps Lumify® Ultrasound devices to train students to conduct and interpret sonographic images. Moreover, the Complete Anatomy® program is made available to all our students. CONCLUSION: The layout of our newly created Anatomy Facilities allows for all aspects of modern medical education mentioned in the literature. These educational modalities and teaching approaches are highly appreciated by our faculty and students. Moreover, these technologies allowed for a smooth transition from on-site anatomy teaching to online education during the COVID pandemic.

Exploring IoT Vulnerabilities in a Comprehensive Remote Cybersecurity Laboratory.

With the rapid proliferation of Internet of things (IoT) devices across various sectors, ensuring robust cybersecurity practices has become paramount. The complexity and diversity of IoT ecosystems pose unique security challenges that traditional educational approaches often fail to address comprehensively. Current curricula may provide theoretical knowledge but typically lack the practical components necessary for students to engage with real-world cybersecurity scenarios. This gap hinders the development of proficient cybersecurity professionals capable of securing complex IoT infrastructures. To bridge this educational divide, a remote online laboratory was developed, allowing students to gain hands-on experience in identifying and mitigating cybersecurity threats in an IoT context. This virtual environment simulates real IoT ecosystems, enabling students to interact with actual devices and protocols while practicing various security techniques. The laboratory is designed to be accessible, scalable, and versatile, offering a range of modules from basic protocol analysis to advanced threat management. The implementation of this remote laboratory demonstrated significant benefits, equipping students with the necessary skills to confront and resolve IoT security issues effectively. Our results show an improvement in practical cybersecurity abilities among students, highlighting the laboratory's efficacy in enhancing IoT security education.

Achievement of learning outcomes in non-traditional (online) versus traditional (face-to-face) anatomy teaching in medical schools: A mixed method systematic review.

In recent years, the logistical challenges posed by the Covid-19 pandemic have prompted medical educators teaching gross anatomy to explore an expanded use of online instructional modalities. There is concern that this shift to online anatomy education in medical schools could affect long-term learning outcomes for future healthcare providers. In this systematic review, the educational effectiveness of online anatomy teaching is compared with traditional ("face-to-face") teaching methods, specifically in terms of students' academic performance and satisfaction. A search of four databases identified and screened 162 studies. Subsequently, 31 studies were analyzed, including both (a) teaching outcome measures (test scores) and (b) student satisfaction ratings. Authors chose studies, extracted data, assessed quality and examined risk of bias. Nineteen studies compared students' academic performances between online and face-to-face teaching methods. Twenty-six studies measured students' levels of satisfaction in both teaching methods. Both qualitative and quantitative analyses of the data revealed comparable academic performances with no statistical difference between the two teaching methods, but a higher level of satisfaction with face-to-face teaching. The findings confirm that students can learn from online teaching but are more satisfied with face-to-face teaching. The authors conclude that online teaching cannot replace traditional teaching and there is no preference for one type of modality over the other. Therefore, a multi-modal learning approach combining online with face-to-face educational modalities for medical students could be efficient and successful.

How To Prepare for the Unexpected: a Public Health Laboratory Response.

Public health laboratories (PHLs) continue to face internal and external challenges to their abilities to provide successful, timely responses to public health crises and emerging threats. These laboratories are mandated to maintain the health of their communities by identifying, diagnosing, and warning constituents of potential and real health emergencies. Due to the changing characteristics of public health threats and their cross-jurisdictional nature, laboratories are facing increased pressure to ensure that they respond in a consistent and coordinated manner. Here, the Association of Public Health Laboratories (APHL) Emerging Leader Program Cohort 11 members have compiled stories from subject matter experts (SMEs) at PHLs with direct involvement in crises to determine the characteristics of a successful response. Experts examined a diverse selection of emerging threats from across PHLs, including infectious diseases, opioids, natural disasters, and government shutdowns. While no public health crisis will be identical to another, overarching themes were consistent across subjects. Experiences from SMEs that could improve future responses to emerging threats are highlighted.
