    【Abstract】 Objective Through the external quality assessment，to investigate the provincial testing level and find the source of problems in AIDS antibody screening labs and improve the testing level and quality. Methods The external quality assessment scheme was established according to National Guideline for Detection of HIV/AIDS. The data from the laboratories was analyzed statistically. The testing level of laboratories was evaluated. Results A total of 94 laboratories were subjected in the external quality assessment. 81 laboratories (86.2%) were qualified, 8 laboratories (8.5%) produced unsatisfactory results, and 5 laboratories (5.3%) were unqualified. Conclusion The majority of screening laboratories meet high quality testing level. Only a few of laboratories failed to meet required qualification and should enhance the quality control. The EQA scheme is useful for finding problems and improving the detection ability of screening laboratories. ......
