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

If someone gets blood drawn to determine cause of illness, could HIV be detected although it's not specifically a HIV test?

If someone gets blood drawn to determine cause of illness, could HIV be detected although it's not specifically a HIV test?

No: To find HIV, the lab would have to do an HIV test to look for it. Otherwise, there would be no way to see if there is any HIV. Only an HIV test can detect HIV. Adults can get HIV screening tests ordered with their regular check-ups, if they are sexually active and/or have risk factors for catching HIV. ...Read more

1.0 A POSITIVE TO HIV TEST?

1.0 A POSITIVE TO HIV TEST?

Probably not: There are at least 20 different HIV blood tests in use around the world, with different cut-off values for positive results. For most or all, 1.0 is negative.

Are rapid hiv test effective ?

Are rapid hiv test effective ?

Yes, but...: ...enough time must have passed since the last possible exposure. The laboratory blood tests all are conclusive within 6-8 weeks, and the 4th generation ("duo", "combo") tests at 4 weeks. The oral fluids home test takes longest of all, up to 3 months to be conclusive. So if you are concerned about a recent exposure, best to go to a doctor's office for proper counseling and testing. ...Read more
