Comparison of methods for the detection of from South African women attending antenatal care.

The detection of using culture assays is challenging. This study aims to compare different assays for the detection of . This cross-sectional study was conducted at King Edward VIII Hospital and included 307 antenatal attendees, each willing to provide two endocervical swabs. The first swab was used for culture identification of , and the second swab was processed for the detection of the pathogen by the TaqMan quantitative polymerase chain reaction (qPCR) assay, an in-house () PCR and PCR detection of the gene. Culture and the nucleic acid amplification assays were each used as comparator tests in the analysis. Sensitivity and specificity were calculated using RS Studio. The prevalence of was 7.8%. When compared to the TaqMan assay, the PCR exhibited the highest sensitivity of 62%, with a substantial level of agreement (kappa level of agreement: 0.60), followed by the PCR (38%) with a moderate level of agreement (0.52) and culture exhibiting the lowest sensitivity of 25% with a fair level of agreement (0.38). The diagnostic accuracy of all the assays was >90%. The TaqMan qPCR assay has the ability to serve as a future diagnostic assay for the detection of .
