Human Immunodeficiency Virus (HIV) Antibody Test by Titration (Serum/Plasma)

What This Test Measures

The HIV antibody test detects specific proteins (antibodies) your immune system produces in response to HIV. The titration process compares antibody levels to identify whether you have a detectable immune response to the virus, which can indicate past or current infection.

How the Test Works

A small blood sample is drawn and analyzed using immunoassay techniques. The test checks for the presence and concentration of HIV antibodies, which may take time to develop after infection. Titration helps determine the exact amount of these antibodies, aiding in diagnosis and follow-up care.

Why It Matters in Diagnosis

Titration is particularly useful for confirming HIV infection in individuals with early or weak antibody responses, such as those recently infected or with suppressed immune systems. It can also help assess viral exposure in cases where initial tests are inconclusive.

Sample Collection and Preparation

This test uses serum or plasma from a blood draw. No special preparation is needed, but fasting may not be required unless instructed by your healthcare provider. The sample is processed and sent to a lab for analysis.
