Not a test for lupus: The HIV test is not a test for lupus. What's clear is that you don't have hiv. You'll never know why your elisa was positive and then indeterminate, and it's not worth investigating. False positive elisas are not uncommon; that's why they have to be confirmed with western blot. ...Read more
Yes: There are 2 reasons for this kind of result: (1) a false positive, or (2) early infection before seroconversion.

The new 4th generation antigen/antibody tests will eliminate this problem. ...Read more

Negative blood test for hiv. Possible that it hit window of seroconversion. How often do you see false negatives after 1-2 months?
Never in my career: False negative HIV means there is infection but the antibody test is negative. The situations where this occurs have to do with the timing of the test or continued risky behavior where a person is infected within days after the test. The home kits that use oral fluid are false negative 1 out of 12, according to cdc website on HIV testing. The blood test done at the right time is very accurate. ...Read moreSee 1 more doctor answer
How accurate for 3 week blood test on HIV and std? If positive or negative isn't it 100%? Do i need to test anymore? Still waiting for results
Let me explain: Standard antibody HIV testing can have two stages. The most commonly used initial screening test is either an enzyme immune assay (eia) or the enzyme-linked immunosorbent assay (elisa). If the eia/elisa test is negative, no additional testing is done. If the eia/elisa screening test is positive, that result must be confirmed with a more specific test called "western blot.". ...Read more
Hi. I had unprotected sex with a guy. I went 30 days after exposure and got a blood test for hiv and syphilis they came back - Should I trust this ?
Retest at 3&6 months: For HIV, it can take up to 6 months after exposure to develop the antibodies that are detected by the test. So retesting is recommended usually at 3 and 6 months post-exposure. For syphilis, antibodies can take several weeks to be produced, so again, if you are concerned, another retest in the future may be indicated. Testing for other STDs such as chlamydia and gonorrhea is recommended also. ...Read moreSee 4 more doctor answers

HIV paranoia: I appreciate your question. It reminds me of the days i began getting HIV tests after my cousin died in utah in 1984 from HIV after a blood transfusion. I was sure that just being around her had someone how made me more susceptible. But, of course the answer to your question is no. There is no such test that a lab would do.
