Correlation between rapid HIV testing and fourth-generation ELISA results for HIV detection among pregnant patients in the delivery room.

Objective: To analyze the usefulness of rapid HIV testing in pregnant patients in the delivery room.

Methods: This prospective study compared a rapid test and a fourth-generation enzyme-linked immunoassay (ELISA) for HIV screening among pregnant patients admitted in labor with an unknown HIV status at a university hospital in Mexico between July 2015 and February 2016. Pearson correlation analysis was performed, and the diagnostic accuracy of the two tests was assessed with HIV RNA polymerase chain reaction (PCR) as the reference method.
