Thirdly by pcr (polymerase chain reaction) which ...Read more

No: It is recommended that you test also at 24weeks which would be 6months. Rarely does the test become positive after this but on a few occasions seroconversion had taken up to a year to occur.

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 more

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

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 more

When dr orders "serious infection" blood test like hiv, does lab secretly take personal info from blood - like your DNA / gene info to identify you?

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. There is also no interest in the lab about identifying you in any way. ...Read more
