Question

How accurate are rapid tests for HIV diagnosis?

Hi, I have been having sex with my girlfriend for the past year and a half. The first few times we had unprotected sex. After that we started using condoms for birth control. We continued to have oral sex often.

Recently my girlfriend developed an ulcer in the clitoris. She then checked and tested positive for HIV-1, by a TriDot test and also by western blot. I myself have tested negative by TriDot as well as by DNA amplification tests. How can i really be sure that i am negative? Should i be taking any prophylaxis?

Answer

The Tri-Dot test is a rapid HIV antibody test that is very accurate and sensitive at detecting HIV infection. Getting a negative result means that you are HIV-negative.

If you have been potentially exposed to HIV over the 3 months before taking the test – I don’t think this is the case because you have been using condoms – then you could confirm this with another test in three months.

Your girlfriend will now need to have other blood tests including a CD4 test to check whether HIV has damaged her immune system and whether she needs to start treatment, and a viral load test if this is available in your country. She should also see a doctor about the ulcer.

You do not need to take any prophylaxis treatment for your own health, but you will need to make sure you continue to use a condom during sex.

The following link show results that show that the TriDot test has over 99.9% reliability.

  2. Herpes is a much easier infection to catch than HIV. However when one infection occurs the risk of the second is often higher. This doesn’t mean that you are likely to have HIV, but you should still have the routinely recommended confirmation test 3 months after your last has sex. Please see your doctor about treatment to manage the herpes infection.
