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 Zinhle,

    You shouldn’t worry. But it’s important that you continue NVP for the right number of weeks to protect your baby. Please talk to your doctor and check how long the NVP is needed. You can also let them know there was a four day break.

    Hi
    I’m HIV+ and my baby is now 4moths old, Her PCR test at 10 weeks came back negative and she is on Bactrim now.(was on Nevirapine for 6weeks). I am exclusively breastfeeding, but my baby has had flu for 2 weeks now, when I went to the clinic I was told to give her 1/2 spoon of honey before bedtime as they advice against exposing babies to different medications under 6months. But she isn’t getting any better, I am thinking of taking her to a doctor so she can get medication coz I feel like the more she is sick the easier it is for her to b HIV+ as she becomes weaker. All this panicking is also causing me alot of stress and worry.

    Hi Chrissy,
    As you can see on the answer above, it’s good that your baby tested negative at 3 months. Please ask your doctor about Ilvitrim. It contains two antibiotics and is used to treat or prevent infections such as chest infections. The doctor will tell you why Ilvitrim is important for your baby and how long it needs to be used for.
