Hello and welcome to e health forum.
It is natural to be anxious when posed with the question, of possible infection with a incurable disease âlike HIV. â
But, you need to understand, that a person gets infected only when the partner in question, infact is âinfected with HIV, and has very high titres. ââ
Though, the risk of infection, by just genital contact, without complete intercourse is comparatively âvery less, than that due to complete intercourse, the risk is still present.â
The best time to do a ELISA test for HIV antibodies is after 4 weeks of exposure. 90% of normal âindividuals who have HIV exposure, will seroconvert within 4-6 weeks. The sensitivity of the ELISA test âis 99.9%. â
If a test once done after 12 weeks of exposure - is NEGATIVE, the chances of developing antibodies to âHIV at a later date will be negligible. Hence there is no need to repeat the test again. â
I hope this helps.
