Question

How many tests are needed to know if a baby is negative?

Answer

Hi

This is likely to be different in different countries and also depending on the risk to the baby

In the UK the baby is tested at birth, 6 weeks and 12 weeks using a test similar to viral load. The test name is HIV DNA PCR. If these tests are negative and the baby has not further risk, then the baby does not have HIV.

HIV antibody tests are not used because a baby keeps the mother’s antibodies for the first 18-24 months. So testing positive using an antibody test doesn’t mean anything until 18 to 24 months old.

Please ask your doctor about how this is tested in your country.

    Hi Prudence, it is great that you started taking ARVs when you did. It is very likely that your baby will stay HIV negative. Many women all over their world find out their HIV status later than you and go on to have healthy HIV negative babies.

    Now that you have started your baby on formula, can I check that you are not breastfeeding? Mixed feeding does increase the risk of transmission. Also, even though that baby is being formula fed, are you still giving them any medication that was given for them when they were born?
