Hi there, and thanks a lot for contacting the AIDS Vancouver Helpline for your HIV/AIDS related health information. It seems you're concerned about the possibility of HIV transmitting during an encounter, and about the accuracy of some tests you've had. We're happy to answer your question for you.
Here is a bit of information on the tests you've had done:
|Test Name ||Method ||Window Period ||Conditions |
|NAAT (PCR RNA & DNA) ||Nucleic-Acid Amplification Testing (NAAT) looks for the genetic material of HIV and tests for it with a Polymerase Chain Reaction (PCR) test. || 2-3 weeks post exposure ||NAAT tests generally take two forms: DNA PCR and RNA PCR tests. DNA PCR NAAT tests are usually used for screening babies of HIV+ mothers. RNA PCR NAAT tests are often used to screen blood or organ donations. Both measure the viral load of a positive person’s blood. Conclusive at 3 months post exposure|
| Enzyme Immunoassay Antibody (EIA) 3rd Generation (ELISA) ||Blood test that looks for antibodies. || Up to 95% of infections are detectable within 4-6 weeks post exposure. Most people develop detectable antibodies in 21-25 days. || Most commonly available testing method. Conclusive at 3 months post exposure. |
You'll see that both of these tests are considered conclusive, meaning their results are taken as accurate, 3 months post exposure. You've had these tests 1 year post exposure, so their results are accurate and your status is HIV negative. These tests are testing for multiple strains of HIV so are capable of detecting "superinfections."
Thanks a lot for contacting the AIDS Vancouver Helpline with your question, we hope it has been answered fully.
