OBJECTIVE: To investigate the application value of chemiluminescence method (CMIA) detection of Treponema pallidum (TP) specific antibodies in the blood test.
METHODS: Over the same period the de novo enzyme linked immunosorbent assay (ELISA) and Abbott chemical luminescence method were used to detect the specific antibody of syphilis in a total of 66298 samples; TP-ELISA negative and TP-CMIA positive unpaid blood donation blood samples for syphilis specific antibody were detected and confirmed by Western blot.
RESULTS: Blood samples from 66298 blood donors were detected by TP-ELISA, the positive samples was 250 and the positive rate was 0.38%. The positive samples of TP-CMIA was 297, the positive rate was 0.45%, the difference was statistically significant (P<0.05). The blood samples of 47 unpaid blood donors were confirmed by TP-Western blot method, as a result, 32 samples were positive, 15 were negative, and result detected by TP-ELISA method was negative.
CONCLUSION: TP-CMIA sensitivity is higher than that of TP-ELISA, and possesses higher sensitivity and specificity, and quick detection, simple operation, easy automation, suggesting greater application value in blood detection of Treponema pallidum.
