What is an HIV test?

You can find out if you have become infected with HIV by having a blood test done. The test doesn't look for the virus itself but for antibodies to the virus. Antibodies are made in your blood when an infection has got into your body.

When should I get an HIV test?

It can take up to three months after infection with HIV before the antibodies show up in your blood. These three months are called the window period. A test done before these three months are over isn't reliable because a blood test may find no antibodies and so you will appear free of HIV, even though the reality is that you have been infected (and could pass HIV on to others).

What do the results mean?

If you have a test three months after you've run the risk of getting HIV and no antibodies are found the result is said to negative and you are almost certain not to have HIV. But if you take risks again you could become HIV positive later on. A negative HIV test doesn't protect you from getting infected in the future.

If antibodies to HIV have been made in your blood then the test result is positive and you have HIV. This means that you could pass it on to others through unprotected sex, giving blood or sharing needles if you inject drugs. If you did any of these during the time between getting HIV and having the test then you may have passed on the virus during that period, and should tell those involved so that they can have an HIV test too.

HIV test results are reliable. To make sure no-one is given the wrong result, a positive result is only given after the blood has been tested several times.

Where can I get an HIV test?

HIV tests can be done at the following:

• a Terrence Higgins Trust Fastest clinic
• a genito-urinary medicine (GUM) clinic or specialist HIV clinic
• your family doctor or at a private clinic

You can choose where you go, bearing in mind that each option has advantages and disadvantages.
