Why This Test Is Done

Your healthcare provider may order this test if you have symptoms of HIV (such as fever, fatigue, or swollen lymph nodes), recently had unprotected sex, share needles, or have been exposed to HIV. It can also be used during pregnancy to check for HIV status or if you have a high-risk behavior.

How the Test Works

A small blood sample is taken from your arm. The sample is tested for HIV-1 RNA using a probe-based amplification method, which identifies genetic material from the virus. This test is highly sensitive and helps confirm HIV infection earlier than antibody tests.

Sample Collection and Preparation

Blood is drawn into a tube that contains an anticoagulant to prevent clotting. The sample is then processed and sent to a lab for analysis. Results are typically available within a few days.

What the Results Mean

A positive result means HIV-1 genetic material was found, indicating an active infection. A negative result means no detectable HIV-1 RNA was found in this sample. Follow-up testing may be needed to confirm or monitor the infection over time.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

What does a positive result mean?
A positive result confirms HIV-1 infection and requires immediate medical evaluation. Treatment can begin right away to control the virus, reduce its damage to your immune system, and improve your health. Early treatment also helps prevent HIV progression and transmission to others.
What if I have a negative result?
A negative result means HIV-1 RNA was not detected in this sample. However, HIV can sometimes take weeks or months to produce detectable RNA levels. If you suspect you may have been exposed, follow up with your healthcare provider for additional testing (e.g., antibody tests) or a repeat RNA test if recommended.
How often should I get this test?
This test is typically not routine for people without symptoms or known exposure. If you are at high risk for HIV (e.g., unprotected sex, sharing needles, or having an HIV-positive partner), your healthcare provider may recommend regular testing. For pregnant women or those with ongoing risk factors, follow your provider’s guidance on testing intervals.
