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

Does getting a non-reactive result on an HIV test mean negative? Even with that result can you still be infected?

Yes, : Yes, non-reactive is negative. But you need to know a little more. There are two main ways of looking for HIV infection--by looking for the body's response to the virus (antibody tests) and looking directly for the virus. In the case of antibody tests (such as elisa and western blot) it may take 6-12 weeks to become "positive" (or rarely up to 6 months), so you can be "non-reactive" shortly after catching the disease, but still be harboring it. The test for the virus itself becomes positive much earlier in an infection, but is not generally described as "non-reactive" when it is negative. ...Read more
