Appraision for experimental verification in methods of blood serum marks in qualitative test at anti-HCV

Objective To appraise and analysis for experimental verification in methods of blood serum marks in qualitative test at anti-HCV.MethodsUsed weak positive blood serum of controled at HCV blood serum marks by NCCL appointed.Carry out make up +20%、-20%critical concentration in assigned item,Carry out test,establish our critical concentration.test weak positive blood serum of controled at HCV blood serum continual 20 d,calculate s/co,CV.Used blood serum of controled of anti-HCV at EQA by NCCL,Test anti-HCV,calculate accorded rate of positive and negtive.ResultsCritical concentration at HCV blood serum in our laboratory were:critical concentration:1 NCU/ml.It was 100%that accorded rate of positive and negtive of HCV blood serum marks.CV of precision daily:≤11.46%.ConclusionIt satisfied demand that experimental verification in methods of blood serum marks in qualitative test at HCV,Its Appraision was simple and easy,It was same that critical concentration in assigned item between our Laboratory and manufacturer gived.It must verification methods indexes manufacturer gived directly.It must establish its critical concentration in experimental verification in methods indexes of blood serum marks in qualitative test at anti-HCV at every Laboratory.
