Analysis estimates test sensitivity for antibody detection in primary syphilis, indicating distinct accuracy levels.

Evaluate the sensitivity of non-treponemal and treponemal antibody tests during primary syphilis diagnosis.
Compared sensitivity of TRUST and RPR tests against darkfield microscopy and PCR.
Calculated sensitivity percentages using samples from patients diagnosed with primary syphilis.
Analyzed data from multiple antibody tests including TPPA.
TRUST sensitivity was 55% compared to darkfield microscopy.
RPR sensitivity was 78% and 93% compared to DFM and PCR respectively.
TPPA showed high sensitivity of 95% against DFM and 96% against PCR.

Sweitzer et al. (2026) studied this question.
