RESUMO
Objective: The epidemic which caused by the SARS-CoV-2 virus were defined as COVID-19) and declared as a global pandemic by the World Health Organization (WHO) on March, 2020. Nowadays, many biochemical parameters related to the diagnosis and prognosis of COVID-19 are being investigated. Therefore, we aimed to evaluate D-dimer and neutrophil/lymphocyte ratios (NLR) of COVID-19 patients whom applied to Karapinar State Hospital. Methods: Patients which consisted of 2523, whom diagnosed with COVID-19 between 11 March 2019 and 29 July 2021 at Karapinar State Hospital were included in the study. Age, gender and social history of the patients were recorded. From the results, the relationships between D-dimer and hemogram were evaluated. Results: There was a high correlation between the variables HCT and HGB, PLT and PCT, NEUT# and WBC, and MCH and MCV (r=0.981, r=0.944, r=0.923, r=0.925). In addition, there was a high correlation between RBC and HCT and between RBC and HGB variables (r=0.852, r=0.795). There was a moderate correlation between WBC and MO#, MCHC and MCH, PDW and MPV (r=0.562, r=0.639, r=0.64). All the relationships between these variables were positive, and the value of the correlated parameter increases linearly by unit. Also, the highest positive relationships were between HCT and HGB, PLT and PCT, NEUT# and WBC, MCH and MCV. Moreover, D-dimer and NLR were not correlated (r= - 0.015, p=0.49). Conclusion: In the study, no correlation was observed between D-dimer and neutrophil/lymphocyte ratios of COVID-19 patients. So, more comprehensive and further studies are needed to clarify these results.
