4th generation test 84 days after the encounter

User Profile
Dear doctor,
I took up a HIV DUO CMIA (4th generation test)test 84 days after the encounter. The result came as "non- reactive" and my index was 0.41 and the reference level said that the index has to be greater than 1 to be reactive.
It was also mentioned that p24 test is taken only for patents with "reactive" results.
But i have been having inexplicable diarrhea and fever occasionally.
Do I have to take any other tests or am I safe.
Kindly advise .
Thank You

Hello and welcome to e health forum.

All ELISA tests usually detect HIV antibody definitely within 4 -6 weeks of a ‎infective exposure. ‎

Since you probably, have a normal immune system, it is likely that the latest ELISA test at 12 weeks (84 days) which ‎is negative is a indicative of your HIV negative status. ‎

Hence it can be surely said that you do not have HIV. ‎

With regard to your diarrhea, they could be due to anxiety associated or due to bacterial infections due to food poisoning. They cannot be attributed to HIV. You might consult with your doctor and get a stool analysis, and other tests, to determine the cause of your symptoms.
