The analysis of HCV-Ab detection results

Objective: To analyze the results of HCV-Ab test and discuss the countermeasure of problem-solving. Methods: The results of HCV-Ab detected by ELISA in 2009 linking with the external quality assessment of nationwide blood bank were analyzed. Results: 24 569 U (200 ml=1 U) blood were collected in 2009 and 360 U blood were abandoned altogether owing to HCV-Ab by ELISA, among reported 162 U as positive, reported 178 U as suspect. The rate as suspect was 55.00%. The accuracy rate of 0574's result was 35.51% in the third time external quality assessment of blood bank in 2005. Conclusion: The HCV-Ab test exists false positive and false negative in blood bank. Testers should reduce waste and insure safety of blood by improving the reagent quality and the test method.
