What Does This Test Measure?

The screening part detects HIV-1 antibodies (proteins your immune system produces in response to the virus) using immunoassay methods. The confirmation part may also include antigen detection (early viral proteins) to confirm active infection.

Why Is This Test Important?

Early detection allows for timely medical intervention, which can improve long-term health outcomes and reduce the risk of spreading HIV to others.

How Is the Sample Collected?

A blood sample is drawn from a vein, typically in your arm. This is a standard procedure and usually done in a clinic or lab setting.

What Are the Possible Results?

Results may be categorized as negative (no HIV detected), positive (HIV confirmed), or indeterminate (requires further testing). Follow-up instructions will be provided by your healthcare provider.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

HIV-1 antibody and antigen detection is critical because it helps identify infection at various stages. Antibody tests detect past exposure, while antigen tests can detect active infection earlier. This panel ensures reliable diagnosis and guides treatment decisions.

Frequently asked questions

What if I Get a Positive Result?
A positive result means you likely have HIV. Your healthcare provider will discuss next steps, including treatment options, support services, and how to manage your health.
How Often Should I Get Tested?
The frequency depends on your risk factors (e.g., sexual history, exposure, or medical conditions). Your doctor will recommend a schedule based on your individual needs.
Can I Get HIV from a Blood Test Sample?
No, the blood sample is processed in a sterile lab environment, and the risk of exposure to HIV from the test itself is extremely low.
