Thirdly by pcr (polymerase chain reaction) which ...Read more

I did 4th Generation HIV test after around 4,5,6,7,8,9,10,11,12,14,15 weeks of an exposure. Is this 100% conclusive? can i get back safely to my wife

Sero-conversion: The whole concept of delayed sero-conversion dates back to old & sloppy tests. PCR testing now will show virus in the blood with or without antibodies. If you need to cling to the old adages...at 6 months..99.99% of the population will have developed antibodies after an exposure..thus the 6 month window. I believe a colleague of mine Lyssette Cardona, MD is in Dubai..she's one of the best!! ...Read more

Yes, conclusive: All existing HIV tests, including rapid blood tests, are conclusive at 5+ monhs. In fact, this test would have been conclusive at 6 weeks. For sure you don't have HIV. Don't waste money or energy on additional testing. ...Read more

Rapid HIV finger prick test at 26 weeks after unprotected sexual encounter. Result was negative how accurate is this result ? Shall I retest?

Rapid HIV finger prick test at 26 weeks after unprotected sexual encounter. Result was negative how accurate is this result ? Shall I retest?

I wouldn't: The odds of a false negative are very low. The gold standard is a nucleic acid assay and if you have obsessive thoughts that you may be positive, this is an option. Otherwise, put the event behind you, learn from it, hopefully cherish having been loved in any case, and be thankful for good health. ...Read more

I have had HIV test done 1 mounth after the expousere with p24 and finger prick trst after 3 mounths all came negative do I have yo do test for hiv1/2?

Confusing question: If you had an indeterminate HIV eia and western blot initially, potential causes for this include partial seroconversion during acute HIV infection or infection with HIV 2. If you are in a low risk category, and your repeat serologic testing and RNA testing at three months was negative, then it is extremely unlikely that you are infected with hiv. Your negative rapid test supports this conclusion. ...Read more

Negative HIV test after 27 days exposure. I use condom, but my mouth and finger touch sex worker virginal liquid. So any change HIV test second time?

The question is?: I'm not sure of your question, but it sounds like you may have come into contact with the HIV virus. Your blood test at 27 days after exposure was negative and you want to know what to do now? You should check an HIV test at 6 weeks and 6 months after exposure. If both are negative, you are 'good to go.' between now and the 6 month mark you should act like you have HIV - so you don't pass it. ...Read more
