Abstract
Objective To confirm the cut off value of commonly used laboratory reagents in ELlSA.Methods Samples are detected according to Their kit introduction and related SOP.The mean,standard deviation and X±3sd were calculated and compared with those calculated by the kit provided.If X±3sd value of project closed to that provide by the kit,the cut off value provided by kit was suitable.Results For HBsAg,anti-HIV,anti-HCV-IgG,anti-TP,the confirmation results were:0.0554、0.0552、0.1753、0.1382,They are different from the values provided by the kit.Conclusion The cut-off valuses of HBsAg、Anti-HIV、Anti-HCV-IgG and anti-TP are usnsuitable due to big discrepancy from the kit.
