Grimes RM, et al. - Via this study, researchers examined if HIV testing in pregnancy identifies women who previously were not known to be HIV positive and the time when in pregnancy women are identified as HIV infected. Further, they assessed if HIV seroconversion occurs during the prenatal care period. From two primarily indigent care hospitals in Houston, TX, they reviewed medical records of 97 women who were found to be HIV positive at delivery. Of these, 30 women were HIV positive prior to pregnancy. During prenatal care, HIV positivity was revealed in 56 women and the seropositivity of 44 women was found before the 34th week of pregnancy. Seropositivity was recognized in 10 women at their first prenatal visit, which occurred after the 34th week. HIV positivity was discovered at delivery in 11 women who received no prenatal care this suggests the great significance of testing for women who do not receive prenatal care. No HIV-positive woman was identified with HIV testing at delivery among those who had tested negative during prenatal care.
