1) A Modern ELISA HIV test is extremely accurate. A NEGATIVE HIV test is CONCLUSIVE at 3 months.

2) A DUO test Antigen/Antibody assay is essentially two tests designed to detect recent infection (antigen) and antibody production (later). Keep in mind that HIV antigens are only detectable for about 3-4 weeks post -infection. By this time, antibodies are produced suppressing antigens but now these would be detected themselves. A completely reliable test when taken at the appropriate time.

If one suspects they have been recently infected, they are advised to test vis an ELISA antibody test @ 6 weeks.  IF that test was NEGATIVE, they should retest @ 3 months for a CONCLUSIVE result.

so wat u r saying is either way for the DUO test it will test for p24 antigen and antibodies if they were any

CORRECT?

[JeanClaude]

The DUO test is indeed designed to eliminate any possibility of HIV infection. The antibody assay would in fact detect any HIV antigens.  This said, the antibody assay's accuracy is limited by the body's immune response. A conclusive negative in the US is STILL determined by a NON-Reactive ELISA at 3 months.
