THE EXTERNAL QUALITY ASSESSMENT OF HBSAG IMMUNOASSAY IN CHINA

Zheng Huaijing Wang Lunan, Wang Wenli, et al, National Center for Clinical Laboratories, Beijing 100730  
Aim: To investigate and improve the quality of HBsAg immunoassay in China. Methods: The definiled serum samples for HBsAg immunoassay were distributed to all laboratories participating the ex- temal quality assessment (EQA ) scheme. Then. the retumed data from the laboratories were analyzed statistically. Results: From 1989 to 1996, the rate of the participating laboratories obtaining annual quality score 10 in HBsAg detection increased from 17% to 64%. The assessment of methods used by the labora- tories showed that the rate of the laboratories using ELISA for HBsAg assay has increased from 77% in 1989 to 92% in 1996. meanwhile, RPHA with low sensitivity has not been usad by the laboratories in 1996. The clinical assessment on HBsAg assay kits showed that the quality of the kits was markedly improved as the EQA scheme had been carried out. Conclusion : The application of the EQA scheme for HBsAg immunoassay in China is useful to the improvement of performance of HBsAg detection in clinical laboratories and the quality of HBsAg assay kits.
