Abstract:
ObjectiveTo investigate the clinical application value of enzyme-linked immunosorbent assay (ELISA) and time-resolved fluorescence analysis(TRFIA) and latex immune chromatography (GICA) in detecting hepatitis B serum markers.MethodsOne hundred and forty-five suspected patients of hepatitis B were detected serum markers of hepatitis B by ELISA,TRFIA and GICA method,and the results were compared and analyzed.ResultsWhen TRFIA method was as gold standard,the positive coincidence rate of ELISA and GICA method in HBsAg,HBeAb,HBcAb was 71％ (57/80),45％ (36/80),and in HBsAb,HBeAb,HBcAb was 33％( 1/3),0 (0/3),and there were significant differences between two methods (P＜0.05 ) ; the others were no significant differences (P ＞ 0.05 ).There was significant difference in the sensitivity of HBsAg between ELISA method and GICA method (P ＜ 0.05 ),but there was no significant difference in HBsAb,HBeAg,HBeAb,HBcAb(P ＞ 0.05 ).There was no significant difference in the specificity of HBsAg,HBsAb,HBsAg,HBeAb and HBcAb between ELISA method and GICA method (P ＞0.05).There was significant difference in HBsAg among three methods(P ＜0.05),but there was no significant difference between ELISA method and TRFIA method (P＞0.05),and there was significant difference between GICA method and TRFIA method (P＜0.05).There was no significant difference in HBsAb,HBeAg,HBeAb and HBcAb among three methods (P ＞ 0.05 ); there was significant difference in both HBsAb and HBeAb positive among three methods (P ＜ 0.05),and there was significant difference between ELISA method,GICA method and TRFIA method (P＜ 0.05).ConclusionTRFIA method has supreme measuring range,sensitivity and specificity supreme,but the price is higher;ELISA method is in the intermediate level of three methods and price is cheap,and it as well as TRFIA is suitable for the batch detection; GICA accuracy is low,but quick and simple,it is more suitable for the complement of the first two methods.
