There are many different types of HIV antibody tests. Only a small amount of blood is needed for these tests. As with any medical test, errors are possible. Available data suggest, though, that the great majority of persons who have HIV will eventually develop AIDS in the absence of effective therapy to slow or halt the infection's progression. When you decide to take the HIV antibody test, counseling is strongly recommended both before and after the test to help you sort out your feelings, maintain a healthy lifestyle, and get appropriate medical attention.
Many options are available to persons who have a positive test.
It's important that a person at risk for HIV seek testing early and get appropriate medical attention. It is important to remember the window period between the time when an individual is infected with HIV, and the time when antibodies to the virus can actually be measured. During the window period an individual is capable of transmitting the virus through unsafe sex or needle sharing. Therefore, if you have engaged in any risky behaviors in the six months to one year before being tested, a negative test result may not be accurate. You may want to consider getting re-tested in a few months.
