After 3 months an antibody test is conclusive unless you have an immune disorder then 6 months.
Generally an individual will know this because health issues will lead to this diagnosis earlier in their life.
Once having an HIV scare every health situation gets blamed on an undetectable infection.
People get sick especially during the winter.
Your anxiety and concern is beyond forum help.
You may need to see a professional to help you with your anxiety.
By the way, if you think you infected yourGF with HIV, have her tested at the right time.
Her negative should bring you peace.
Further, i have lost 6 Kg weight in last 1.5 months with regular diet. also i got bumps and pimples on my scalp last month for 2 weeks (gone with treatment). Pl suggest what further to do?
You tested conclusively negative from your risk 3 yrs ago.
You looked for the virus itself, p24, and antibodies and all where negative.
Try and get your anxiety under control, it can't wreck your immune system.
Take a DUO 28 days ((no later)) post exposure as an indication, and follow up with an antibody test at 3 months post exposure for a conclusive result ((as you were advised in your previous posts)).
If this kind of risky behaviour makes you worry so much, why don't you start making a habit of using protection to avoid all the anxiety in the future.
