From: Evaluation of the SD BIOLINE HIV/syphilis Duo assay at a rural health center in Southwestern Uganda

  Sensitivity (95% CI) Specificity (95% CI) PPV (95% CI) NPV (95% CI)
Syphilis (%) 100.0 (79.1 - 100.0) 100.0 (97.7 - 100.0) 100.0 (79.1 - 100.0) 100.0 (97.7 - 100.0)
HIV* (%) 100.0 (75.9 - 100.0) 99.5 (96.9 - 99.9) 94.1 (69.2 - 99.7) 100.0 (97.7 - 100.0)
  1. TPHA – Treponema pallidum hemagglutination assay; HIV algorithm - Determine, Statpak and UniGold tests run serially; Duo kit – SD BIOLINE HIV/syphilis duo kit.
  2. *HIV-syphilis results were obtained from TPHA and HIV algorithm results.
