What's the best HIV Test?
The best HIV test is one that provides you with an accurate and reassuring result in a time frame that suits you best. Everybody will have a different "best HIV test" because their circumstances will be slightly different. The main things to think about are firstly when you were possibly exposed to HIV and secondly how desperately you need to know the answer. The exposure time is important because it allows us to calculate the HIV window period, which is the time from HIV infection to detection.
There is a great deal of confusion regarding HIV testing which results mainly from the enormous leaps in our knowledge about HIV in the time since the epidemic began and the advancement of the technology behind the testing devices.Consequently the question as to which is the best HIV test depends very much on the individual circumstances.
We now have HIV testing methods that will allow us to identify HIV infection very early on indeed. This is important for all sorts of reasons, not least the fact that we know that the key period for passing HIV on to another person is in the first few months after infection, when the amount of virus in the infected person's blood stream, semen or vaginal fluids is likely to be very high. The amount of HIV virus in a body fluid is referred to as HIV viral load and in the early stages is likely to be many hundreds of thousands or millions of copies of virus in each one millitre of blood or fluid.
As the infection proceeds and the newly infected person's body gets a hold on the new HIV infection, the amount of virus falls and that person becomes, we think, much less infectious. So for example, if I were to become HIV positive today, then in around 2 weeks or so my viral load - the amount of virus in each 1ml of my blood or semen - would be rapidly increasing and starting to run into the millions of copies. I would be very infectious to those I had unprotected sex with.
Testing newly infected HIV positive people early allows us lots of opportunities to influence the outcome for the good. We know from studies that most people who are aware they are HIV positive are keen to avoid passing HIV on to others. They certainly do not want a moment of madness on their part to result in their loved ones becoming HIV positive too.
So, what is the best HIV test?
- Testing for HIV 7 days after exposure
Preliminary diagnosis of very early HIV and Hepatitis C disease is now possible at
7 days post possible exposure. This time frame was previously unavailable but utilisation of standard routine technology in a novel diagnostic style will facilitate very early diagnosis. The technique has had most application so far in terms of screening the human blood supply from blood donors and has reduced the numbers of inadvertent contamination with HIV and Hepatitis C virus very considerably. The technique is also employed in organ donation settings where organs to be donated are screened for the HIV-1, HIV-2,Hepatitis C and Hepatitis B viruses.
