do i need further tests?
Hello and thank you for posting your medical question on E health forum.

HIV is diagnosed based on the serological detection in the blood samples. It is not diagnosed on the basis of nonspecific signs and symptoms.

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 45 days (more than 6 weeks post exposure), the ELISA test result is valid and you are HIV FREE.

If the test was done before 28 days, then the chances that you need a retest would be high.

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.
