Antigen p24 combo test
Good morning,

I'd like to know if a 4th generation HIV combo (antigen p24 / HIV1 + HIV2) test is accurate in its results, when they're negative, after 2 weeks (15 days) of a risk exposure.

There are many sites on the internet that say it actually is, but some others deny it.

Can you help me please? Thank you very much!

There are no tests manufactured which can give a conclusive result in 15 days. A conclusive result can be obtained at 12-13 weeks, be it any test.

a combo test at 15 days is too early.  taken at 4 weeks, it is a very good indicator of your status.  follow up at 3 months

I'd like to know if it is true...I'm so scared I had a false negative!

Thanks a lot.

  In an adult, a positive HIV antibody test result means that the person is infected, a person with a negative or inconclusive result may be in the “window for 4 to 6 weeks but occasionally up to 3 months after HIV exposure. Persons at high risk who initially test negative should be retested 3 months after exposure to confirm results
