What if I test positive for HIV during labor?

An initial positive result for HIV during labor requires the delivery team to act immediately to protect both mother and newborn, while conducting urgent confirmatory testing; an initial result alone is not a final diagnosis. The team does not wait for all results to begin appropriate preventative measures. Do not start breastfeeding until the team reviews the follow-up tests and determines a safe feeding plan [6].

What does an initial test result mean?

A rapid test may be performed when HIV status is unknown at the time of delivery. If the result is positive, doctors will order additional tests, including an HIV-1/2 antibody differentiation immunoassay and a viral load (RNA) test on the mother's blood. This helps confirm the infection or rule out a false-positive initial result. Your doctor will explain the meaning of the result and the next steps, and will request urgent priority for these tests from the laboratory [6].

A positive result in the mother does not prove that the baby is infected. The newborn requires their own testing, including a test to detect the virus's genetic material, and follow-up care as determined by the specialist team. It is essential to distinguish between the risk of infant exposure to the virus and a confirmed infection; each requires specific evaluation and a care plan [6].

What happens to the mother and newborn immediately?

US guidelines referenced recommend initiating intravenous zidovudine during labor upon an initial positive result, with other decisions made under the supervision of obstetric and HIV specialists. These are hospital procedures where the team selects dosages based on the specific case; they are not for self-administration. The mother's ongoing treatment plan will be arranged with a specialist based on test results and health evaluation [6].

A newborn at high risk begins presumptive antiretroviral therapy promptly after birth according to the pediatric specialist's assessment. There is no single duration or combination of medications that suits all newborns; the regimen and follow-up are determined by the level of exposure and test results. The plan may change if the mother's infection is ruled out by follow-up tests. Parents should not stop or adjust the infant's medication based on a single result without the team's guidance [6].

How is infant feeding managed while awaiting confirmation?

This situation differs from that of a mother known to be HIV-positive since pregnancy with sustained viral suppression. When a test is positive for the first time during labor, guidelines recommend not initiating breastfeeding while awaiting follow-up tests. Breast milk may be pumped and stored appropriately, but it should not be given to the newborn until all requested tests are reviewed and confirmed negative. Discuss an appropriate infant feeding alternative with the team immediately [6].

Correctly prepared infant formula or pasteurized donor milk eliminates the risk of viral transmission via breast milk, but they do not replace the need for newborn testing and protection against previous exposure during pregnancy or delivery. If the mother's infection is confirmed, her team will determine the subsequent feeding plan according to the circumstances and applicable guidelines [5].

What information do you need before discharge?

Ask for an explanation of available test results, what is still pending, the medication plan for both mother and child, follow-up appointments, and feeding methods. Guidelines recommend documenting the mother's results in the newborn's record and informing their care provider so that follow-up continues without interruption [6]. Regular care and antiretroviral treatment help protect the mother's health and reduce transmission [5]. For broader context, read HIV and Pregnancy: Protecting Mother and Fetus (Arabic).
