Abstract:
Objective To analyze the clinical performance of chemiluminescence immunoassay (CLIA)in determination of trepo‐nema pallidum antibody(TP antibody) .Methods The results detected by enzyme‐linked immunosorbent assay( ELISA)were regar‐ded as relative standards ,and results detected by treponema pallidum particle assay (TPPA) were regarded as recognition criteria . 2 223 serum samples of outpatients and inpatients were collected ,and TP antibodies were detected by CLIA and ELISA method re‐spectively ,and followed by confirmation of TPPA test .Results Among 2 223 serum samples ,53 samples were TP antibody positive detected by ELISA and 60 samples were TP antibody positive detected by CLIA ,and the positive incidence of TP antibody detected by the ELISA and CLIA method was 2 .34% and 2 .65% respectively .The positive predictive value ,sensitivity and specificity of the CLIA method was 98 .33% ,100 .00% and 99 .95% ,repectively .Conclusion The CLIA method could be considered adequate for screening of TP antibody in a large volume of samples ,with characteristics of automatic ,quantitative and short turn around time .
