HIV Antibody Screening Test (Serum/Plasma)

Why This Test Matters for HIV Medication Access

This screening is often required before starting HIV treatment (antiretroviral therapy, or ART) to confirm whether your body has developed antibodies against HIV. Antibodies appear within weeks to months after infection, making this test critical for eligibility.

How the Test Works

The test uses a blood sample (serum or plasma) to identify HIV-specific antibodies via an immunoassay method. If antibodies are present, it suggests past or current infection, which may affect eligibility for certain HIV medications.

What to Expect During the Test

A healthcare provider will draw blood from your arm. The sample is processed and tested for HIV antibodies. Results are typically reported as positive, negative, or indeterminate (requiring further testing).

Interpreting Your Results

A negative result means no detectable antibodies to HIV in your blood at the time of testing. A positive result indicates potential exposure and warrants further diagnostic testing (e.g., HIV viral load or Western blot) to confirm infection.
