Abstract

Abstract Background During HIV retesting in antenatal and preexposure prophylaxis (PrEP) care, discrepant results occur, but guidelines are lacking. Methods In a Kenyan trial implementing antenatal PrEP, if 1 test is reactive, a second is performed; if discrepant, both are repeated; if persistently discrepant, DNA polymerase chain reaction (PCR) is performed. Results Among 4451 women, 23 265 HIV retesting sessions were performed; 14 (0.06%, 95% confidence interval, 0.03%–0.10%) had discrepant results among 10 individuals; in all 10 initial cases, PCR was negative. Conclusions Discrepant rapid tests are an expected, rare, and important challenge for antenatal care HIV retesting, with and without PrEP. Clinical Trials Registration NCT03070600.
