How reliable is the Instant (Rapid) HIV test, especially in detecting sero conversion status within a 4 week period of exposure?

I was recently exposed to a person with HIV + status in the past 5 weeks. i did a Rapid/Instant test with a professional health practitioner and the test was negative. How reliable would the Rapid test be in detecting sero conversion within this period. I'm not certain what Generation the test is. Your advise please.

The rapid tests that we use are 4th Generation ELISA tests. They are able to detect HIV infection within 4 - 6 weeks post-exposure. It is a very good sign that your test is negative at 5 weeks. Test again at week 12 and if that test is negative then you are indeed negative.

I would say 0, rapid tests dont detect acute infections well, even ag/ab, i would suggest you get a proper lab test
