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.
Fourth generation ELISA for HIV1/HIV2
1) 4th generation ELISA is a DUO TEST (Antibody and Antigen Sandwich Test) .It actually looks for the P24 (protein) Antigen and Antibodies simultaneously.
2) P24 Antigen is almost always present in the body after acquiring the virus till the 4th week after infection and then it disappears .
3)Once the P24 antigen disappears,antibodies starts to show up.
As far as I am aware it is a reliable 4th generation test. The time you took it is also the proper and the result is conclusive.
Just so I understand then
a ab/ag is an ELISA that also detects for the p24 antigen aka duo test aka 4th gen test
vs
a standard ab test aka ELISA aka 3rd gen
correct?????
In the test result, it says the following:
Interpretation for methid HIV 1/2 (CLIA)
No Sign of HIV 1/2 Infection with IgG/AgM Elisa
What is this test? Teak do u know it?
Also, it mentions in the units : qualitative. What do they mean by qualitative?

The HIV antibody/p24 antigen Duo Test is an excellent, accurate and inexpensive HIV test that reliably detects HIV infection that occurred just 28 days prior to the test. This HIV test is known as the 'Duo' because it tests for both HIV antibodies as well as the 'HIV P24 antigen'. The HIV p24 antigen is a core HIV viral protein which becomes detectable at approximately 10 days post exposure, peaks at 16 days or so and then remains at high level for 8 to 10 weeks post exposure.
Did you have an ELISA (Ab) test or a DUO (Ab + Ag) test? An ELISA test doesn't check for antigen. If you only had an ELISA test you should test again at 3 months just to be sure. But expect it to be negative.
