    Abstract:Objective Using dot immunogold filtration assay(DIGFA) to establish a new method for detecting anti-sperm antibody in serum of infertile couples.Methods A dot immunogold filtration assay was developed by coating purified sperm membrane antigen on nitrocellulose membrane, labeling SPA with colloidal gold, the whole procedure could be finished in 2-4 min.Results The coincidence rate of the results of simultaneous determination of serum samples with ELISA and DIGFA was 97.7%.DIGFA had an overall specificity and sensitivity of 96.2%(TN/TN+FP×100%) and 88.9%(TP/TP+FN×100%),positive predictive value and negative predictive value of 84.2% and 97.2% respectively.Conclusions Using DIGFA to detect anti-sperm antibody in human serum is more simple and rapid, and is of value for clinical application.9m11-v2, 百拇医药
