How the Test Works

The test uses a specialized probe to identify HIV-1 genetic material (nucleic acids) in your blood sample. This method is highly sensitive and can detect very small amounts of the virus, even when symptoms are not yet present.

What to Expect Before the Test

No special preparation is needed. You may have blood drawn from a vein in your arm, similar to other blood tests. If you’re on blood thinners or have a history of bleeding issues, let your healthcare provider know.

When This Test Is Used

This test is typically ordered during initial HIV screening, as part of routine testing for sexually transmitted infections (STIs), or if you have symptoms that may suggest HIV, such as unexplained weight loss or persistent fatigue.

What the Results Mean

A positive result means the test detected HIV-1 genetic material, indicating an active infection. A negative result means the test did not detect the virus at the time of testing. Follow-up testing may be recommended to confirm results.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

Why is this test important?
Early detection of HIV allows for prompt treatment, which can significantly improve health outcomes and reduce the risk of progression to AIDS. This test is critical for monitoring viral load and assessing treatment effectiveness over time.
What if I get a positive result?
A positive result means you have HIV. Your healthcare provider will guide you through next steps, including connecting you with care, starting antiretroviral therapy (ART), and managing your health. Testing for other STIs and discussing prevention strategies will also be part of your plan.
Can this test be used for routine HIV screening?
Yes, this test is often used as part of HIV screening, especially when combined with other diagnostic methods. It’s particularly useful for detecting HIV earlier than traditional antibody tests, which may take weeks or months to show results.
