Hello, and thanks for your medical question on E Health Forum.

HIV is diagnosed based on the serological detection in the blood samples.

A person after exposure to HIV can get tested as early as 4 weeks to 12 weeks with the ELISA for HIV antibody test. 90% of normal individuals who have HIV exposure, will seroconvert within 4-6 weeks. The sensitivity of the ELISA test is 99.9%.

In your case since the ELISA test was done at 12 , 13 and 17 weeks and was found to be negative. The ELISA test result is valid and you are HIV FREE.

You do not need further testing, anymore. There is no risk of infection to anyone.

Any repetition of tests will definitely be negative at this point.

If you still have doubts, you might consider to consult with your doctor who can provide reassurance and also can clear all your doubts that you may have.

I hope this helps.
