Abstract:
Objective To evaluate the clinical value of the chemiluminescence immunoassay particles (CMIA)in the diagnosis of syphilis.Methods The serum specimens from 150 cases of syphilis in our hospital were selected as the observation group and con-temporaneous 150 serum samples from non-syphilis healthy people were selected as the control group.The toluidine red unheated serum test (TRUST),treponema pallidum particle agglutination test (TPPA)and CMIA were adopted to conduct the detection. The sensitivity,accuracy and specificity of the three kinds of method were calculated and their differences were compared and ana-lyzed.Results The sensitivity of TRUST and TPPA and CMIA was 65.3%,97.7% and 99.3% respectively,the specificity was 74.7%,97.3% and 100.0% respectively,the accuracy was 70.0%,97.0% and 99.7% respectively,the difference among three kinds of methods had statistical significance (P <0.05).The sensitivity,specificity and accuracy of TRUST were lower than those of CMIA and TPPA (P <0.017),there was no statistically significant difference between CMIA and TPPA (P >0.017).Conclu-sion CMIA is equivalent to TPPA in the sensitivity,specificity and accuracy,is superior to TRUST,and has the advantages of sim-ple operation,objective results and good repeatability.
