How the Test Works

The test uses an immunoassay method to identify HIV antibodies in your blood or plasma. Antibodies are proteins your immune system produces in response to HIV infection. If antibodies are present, the test will return a positive result, indicating possible exposure to HIV.

What to Expect Before the Test

No special preparation is needed for this test. You may have a blood draw at a clinic, doctor’s office, or lab. If you are tested as part of a routine check-up, your healthcare provider will explain the process and answer any questions you have.

What to Expect After the Test

After the blood sample is taken, you may feel a brief pinch or discomfort. Most people return to their usual activities immediately. If you experience unusual bruising or bleeding, contact your healthcare provider.

What the Results Mean

A positive result means your test detected HIV antibodies, suggesting you may have been infected with HIV. Follow-up testing, such as a confirmatory HIV antibody test, is required to confirm the diagnosis. A negative result means no HIV antibodies were detected in this test, but HIV could still be present in your body.

Frequently asked questions

Why is this test important?
Early detection of HIV is crucial for managing the infection effectively. It allows healthcare providers to prescribe appropriate treatment, monitor your health, and prevent complications. Untreated HIV can lead to acquired immunodeficiency syndrome (AIDS) and other serious health issues.
What if I get a positive result?
If your initial HIV antibody screening test is positive, your healthcare provider will likely order a confirmatory test to ensure accuracy. This may include a Western blot or another confirmatory immunoassay. You will receive guidance on next steps, which may include counseling, connecting with support services, and starting antiretroviral therapy if needed.
How often should I get tested?
The frequency of testing depends on your risk factors. The Centers for Disease Control and Prevention (CDC) recommends testing at least once every 6 months if you are at high risk. If you are not at high risk, you may get tested once every year or as advised by your healthcare provider.
