When is HIV testing recommended during pregnancy?

HIV testing during pregnancy is recommended primarily during the first trimester for all pregnant individuals. However, for certain high-risk populations, additional testing in the third trimester is advised to ensure that any possible new infections are identified and appropriately managed before delivery. High-risk groups might include women with a history of intravenous drug use, those whose partners are HIV-positive, or women engaging in unprotected sexual activity with multiple partners.

The rationale behind this recommendation is to maximize the chances of preventing vertical transmission of HIV from the mother to the fetus, which can occur during pregnancy, labor, or breastfeeding. By testing in the third trimester, healthcare providers can implement appropriate interventions, such as antiretroviral therapy, which significantly reduces the risk of transmitting HIV to the baby.

This approach aligns with the goal of comprehensive prenatal care, promoting both maternal and neonatal health. While it is essential to perform initial testing early in the pregnancy, recognizing high-risk populations for additional testing later ensures more effective management of both the mother’s health and the prevention of HIV transmission to the infant.
