What is HIV ab, HIV 1/2, eia with reflexes? I had blood work done. Did they test for antibodies and the virus?

Antibody test HIV: It is a test for the two main types of HIV antibody (ab), types 1 and 2. Eia is the primary test method that is inexpensive, but it occasionally has false positive result, so there is a reflex test (automatic confirmation test) using a more expensive but more trustworthy test (immunoblot) to make very sure that the eia test result really is positive. There is a pcr test to detect HIV itself. ...Read more

Was tested using HIV using HIV ab, HIV 1/2, eia, with reflex 65 days from a possible infection, how accurate this test?And should I get tested again?

Yes and no: Usually people tested within the first 3-6 weeks of an exposure can have a false negative, but 65 days out should be enough time to have a positive test, so if it was negative, it's very likely it is correct. That said, if you have had a repeat exposure you are concerned about, you would need to be retested. ...Read more

I just had an HIV 1/2 eia antibody screen w/ reflexes. Can you explain how this test works? Are there any better tests?

Viral Testing: To test for many infections we look for antibodies (your body's reaction to something new or foreign). In the case of HIV infection these antibodies can take three to six months to be positive on a test. This old fashioned test is a reliable and common screening tool. But, it is not the best test if one is possibly exposed. We now send HIV genetic tests which can be positive by day 21 post expos. ...Read more

Good test, reliable: CDC and other experts advise moving away from the "generation" terminology for HIV tests. But this test is one that has been called 4th generation and is highly reliable. It proves you don't have HIV, unless exposed and possibly infected in the 4-6 weeks before the test was done. ...Read more
