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. We're happy to answer your question for you.
Her sucking on your nipples is a no risk activity. You mention checking your nipples to see if there were any cuts that you think could possibly increase the risk of transfer. In reality, small cuts do not increase the risk of transfer. Much larger, gaping wounds are required to increase the risk of transfer to any significant extent. Receiving even unprotected oral sex is considered a negligible risk activity, meaning that while transmissions are theoretically possible, none have been shown to actually occur. We would presume protected oral sex carries with it an even lower risk. To see the risk level of these and many other common activities, we encourage you to check out our [risk assessment page](http://helpline.aidsvancouver.org/question/risk-assessment-chart).
Here is a bit more information on the tests you've had (the COMBO test is another name for the DUO test):
|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|
| 4th Generation EIA ||Blood test that looks for antibodies AND p24 protein antigens. Commonly referred to as the "combination," "combo" or "DUO" test. || P24 protein is detectable immediately after infection but only for the first few weeks. The antibody (ab) test has a window period of 4-12 weeks post exposure. || This test is widely available in North America. Most HIV specialists consider this test to be conclusive at 6 weeks but official HIV testing guidelines still recommend re-testing at 12 weeks for conclusive results. Conclusive at 3 months post exposure. |
You'll see that common with the tests you've had are that they are not considered conclusive until 3 months post exposure. Please remember the risk levels associated with the activities you engaged in (at most negligible risk). You do not actually require testing after this specific encounter. However, we at AIDS Vancouver recommend routine testing for all sexually active individuals, so it's great that you've gone for testing. Normally, after higher risk activities, we'd recommend you go for further testing at least 3 months post exposure. This is not required in this case.
Thanks a lot for contacting the AIDS Vancouver Helpline with your question, we hope it has been answered fully.
