HIV antibody(1&2) + p24 Antijen test or Standard HIV antibody test?

Is the content of the stand alone HIV antibody test is the same with the HIV antibody(1&2) + p24 Antijen test?

More clearly, do they test the antibodies in the same way they  considering the final technologies are used in both tests.

Or even more clearly, which of the tests below will be more definitive at 12 weeks and what are their reliability % at 12 weeks;

1. HIV antibody test
2. HIV antibody(1&2) + p24 Antijen test

Thanks..

All tests are conclusive at 3 months post exposure.

Hi Teak,

Sorry but I've read some of your posts implying(or I understand this way) that 3rd generation testing could be better than 4th generation DUO(HIV 1 2 antibody + P24 antigen) at 12/13 weeks. I know that P24 part of the 4th generation test may be useless at week 12, but how about the antibody part of the test? Is it as reliable as the 3rd generation antibody test? If not, I'll take another 3rd generation test.

My previous tests are;

HIV antibody test 3rd gen - Non reactive - 5,6 weeks

HIV antibody(1&2) + p24 Antijen test - Negative - 12 weeks

HIV antibody(1&2) + p24 Antijen test - Negative - 12,6 weeks
