Need an HIV Test?

Getting tested is the only way to know for sure if you have HIV. It’s a good idea to get tested if you’ve had unprotected sex, shared needles, or if a partner has tested positive for HIV. Luckily, HIV testing is easy, and once over with can really put your mind at ease.

What to expect

A counselor will come to get you and take you into a private room. There, your counselor will explain the testing process, answer any questions you may have, and obtain your consent to be tested.

If you agree to be tested, you will proceed to the lab, where a phlebotomist will collect a sample of your blood. This sample will be used to run your HIV test. (If you qualify for STD testing, there will be additional blood taken for Syphilis, and swabs taken for Oral/Rectal Chlamydia and Gonorrhea.)

The STD results come back in 10 business days.

You will then return to the room with your counselor to talk about your risk for HIV and any other related questions or concerns you may have. If you don’t have much to talk about, you may be asked to wait in our waiting room until your result is ready. After 20 minutes (the amount of time that the HIV test takes to run), your counselor will return with you to a private room to disclose the result.

Afterward, you will have another chance to talk to your counselor about any questions or concerns you may have.

What happens if I test positive for HIV?

If you receive a reactive HIV antigen/antibody result it means your test is postive it is very likely that you have been infected with HIV. To confirm the diagnosis, your counselor will ask you to provide a blood sample in order to run confirmatory laboratory tests. Your counselor will also introduce you to someone who can help link you with HIV-specific medical care, as well as other services such as partner notification, or psychosocial support.

What is the window for an HIV test?

The Alere Determine test detects the presence HIV antigens and antibodies. A person’s immune system produces HIV antigens and antibodies after being infected with HIV. The window period is the time between a person’s infection with HIV and the time the body produces a sufficient amount of antigens/antibodies to be detected by the test. People infected with HIV usually develop detectable antigens/antibodies between two weeks and four weeks after infection. If your risk for HIV was less than four weeks prior to your HIV antigen/antibody test, it is possible that the test would not detect the infection.

Alere Determine™ HIV-1/2 Ag/Ab Combo (Determine Combo) is a rapid test capable of detecting HIV-1 p24 antigen and HIV-1 and HIV-2 antibodies. The p24 antigen is a part of the HIV virus and can be detected before antibodies develop. If the test is reactive, the Determine Combo indicates whether the reaction is caused by antigen, antibody, or both. Please discuss the window period with your counselor if you have additional questions.
