I recently wrote in about performing oral sex with ejaculation(swallowing) and testing was not recomended. I went ahead and tested at 43 days after exposure anyways and my test came back non reactive. Like many others I thought my worries would be gone after this yet here I am again with more questions. I apologize in advance if they seem repetitive of others inquiries before.

1. The test taken says HIV1 / 2 ag/ab combo screen. What generation test is this and at 43 days is this conclusive for oral sex?

2. Because my test was taken at 43 days does that mean either the antigen or antibodies would have surely showed up by this time? What would take them longer to show up?

3. Ive read answers on this forum that say 6 weeks is conclusive but if you've been at high risk to test out to 12. Why does the risk have effect on timing ?

4. At the fourth week after exposure I was extremely naseous and fatigued for a couple days. Testing was about two weeks after this. If this was in fact ars would the test have came back reactive?

5. The only reason I am still worrying is because of my constant white tongue. I know symptoms are not used as diagnosis but is this common in early HIV or shows up after years of having the virus? Would this be a reason to retest?

6. Is 6 months too long to wait to retest, could someone get deathly sick in this short time period?

7. Lastly why are some oral exposures recommended testing when others like mine where there was ejaculation and a sore throat present not? Is HIV from oral rare or low risk...

Thank you for your time. Your responses really help me and a lot of people who are struggling or not well informed.

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 a test you've had since then. We're happy to answer your question for you.

As has been mentioned before it seems, giving oral sex is considered a low risk activity, meaning that while transmissions are possible, specific conditions are required (like having major dental surgery just prior to giving oral sex). Having a sore throat will not increase your risk whatsoever. We'll try and answer each of your questions, but keep this in mind when reading the responses, particularly the responses on testing.

Here is a bit more information on the DUO test (or COMBO test):


You can see in the chart that this is a 4th generation test. When we assess whether results are conclusive or not, the risk level of the encounter you're concerned about is not considered. There is of course a certain risk level assigned to the activity you're concerned about, but testing after a period of time will give your results at the same accuracy no matter what the initial risk level was. So a test at 43 days is too soon to say if a transmission indeed occurred after your encounter (but remember that it was low risk to begin with). If you'd like to know conclusively your status after that encounter, you'll need to wait until at least 90 days post exposure.

As we've mentioned before, we at AIDS Vancouver are not healthcare providers, so cannot comment on any symptoms you may be experiencing. However, HIV infections are never diagnosed based on symptoms alone, simply because the symptoms of an HIV infection are quite common to many other common medical conditions. Testing is the only way to diagnose an HIV infection. If you're concerned about any symptoms you're experiencing, we'd encourage you to see a healthcare provider. "ARS" is a term that has been used to describe the symptoms HIV positive people start to experiencing many years after initially being diagnosed.

Thanks a lot for contacting the AIDS Vancouver Helpline with your question, we hope it has been answered fully.

Test Name Method Window Period Conditions
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. |
