Hi Doctor, I had sex with an unknown person on 10 Dec 2015, During sex, condom broke and I might have exposed my penis to a high risk. I have got myself checked four times and the results are as below
CMIA: 9 Jan (after 29 days)- 0.29
Elisa 3rg gen 12 Feb (after about 60 days) - Negative
CMIA: 24 Feb (after 76 days) - 0.21
CMIA: 15 Mar (after 95 days) - 0.1

I have not had any risk exposure (stayed away from sex) since 12 Dec. Should I still be worried?

Hi there, and thanks a lot for contacting the AIDS Vancouver Helpline for your HIV/AIDS related health information. It seems you're worried about the accuracy of some HIV tests you've had after a potential exposure. We're happy to answer this question for you.

As it seems you're aware, if the condom breaks during intercourse this is taken as if it were not being worn at all, so is considered high risk. So it's great you were proactive and decided to go for testing after this situation.

Unfortunately, the only results I can comment on are the ELISA test you had. The CMIA readouts you've given are only meaningful to the professionals administering the test, as the values can vary depending on the lab interpreting the test. What is important when looking at the results from these tests is your current status (positive or negative). As for the ELISA test, here is a bit more information:


You'll see in the chart that while results of this test are a very good indicator of your status currently (at 60 days), they are still not considered conclusive, meaning the results are not taken as accurate. The test you've had at 95 days are, however, accurate. So just take a look at the positive/negative status of that test (or go back to the testing location to have the results interpreted for you) to get your status conclusively.

It's great you decided to use a condom for your encounter, as they reduce the risk of both HIV transmission, and the transmission of STIs. If you're interested, [here is a link](http://smartsexresource.com/topics/condoms) to a very good resource with a lot of great information on using condoms.

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