ABSTRACT
Objective To evaluate the testing capabilities of laboratories,analyze existing issues,and improve testing quality,through carrying out the external quality assessment(EQA)of clinical laboratories for human papillomavirus(HPV)type 6 and 11 nucleic acid detection.Methods EQA plan was carried out twice a year.Each panel contains 4 positive samples,including one strong positive sample and one weak positive sample of HPV6 and HPV11,made from cervical secretions from patients with clinical manifestations of condyloma acuminata(CA)and positive for HPV6 or HPV11(from Shanghai First Maternity and Infant Hospital).One negative sample was cultured from the C-33A cell line(from Chinese Academy of Sciences).Samples were sent to participating laboratories by cold chain,and laboratories were required to detect test samples and upload their results within the specified time.Shanghai Center for Clinical Laboratory(SCCL)calculated the scores of each laboratory based on the return results.Results A total of 163 sample panels were sent out in the 6 rounds of EQA plan and 140 valid reports were received.The laboratory qualification rate was 96.43%(135/140)and the sample compliance rate was 97.86%(685/700).There were 13 false negative results and 2 false positive results,with weakly positive samples accounting for 76.92%(10/13)of the false negative results.Conclusion The detection accuracy of HPV6/11 nucleic acid in each laboratory was relatively high,and the detection ability of weak positive samples in individual laboratories may need to be improved.The laboratory could discover problems and improve its quality management by participating in EQA.
