Do HIV tests need to be repeated after the window period?

Question

Hi doctor,

I did a self-HIV (Human Immunodeficiency Virus) test 45 days after a sexual encounter and tested negative. As the window period for the test is 90 days, I feel the test reports could be inaccurate. Currently, I am taking the tablet Finasteride for hair loss. I would like to understand how likely it is to get a false negative test at 45 days. Should I repeat the test after the window period is over? Please help.

Hi,

Welcome to icliniq.com.

I have read your query and can understand your concern. The home-based HIV (human immunodeficiency virus) tests are very sensitive and accurate if performed according to the instructions. These are antibody tests, so the chances of HIV tests coming positive later are almost nil. But sometimes, if the instructions are not followed correctly, there is a possibility of some errors. These antibody tests are considered conclusive after three months of risk exposure. Therefore, it would be better to go for an HIV antibody test after three months of risk exposure in a reliable laboratory to relieve anxiety and for conclusive results.

I hope this helps.

Thank you.
