HIV - CMIA

HIV - CMIA Test

The HIV – CMIA test is a blood test used to screen for Human Immunodeficiency Virus (HIV) infection. CMIA stands for Chemiluminescent Microparticle Immunoassay, a laboratory technique used to detect specific markers associated with HIV.

Depending on the assay used, an HIV CMIA screening test may detect HIV-1 and HIV-2 antibodies and/or the HIV p24 antigen. Combination antigen/antibody assays can help identify HIV infection earlier than antibody-only testing.

A reactive screening result does not by itself confirm HIV infection. Additional confirmatory testing is required according to the laboratory's testing algorithm. Likewise, a non-reactive result may not rule out a very recent infection because there is a window period between infection and detectability.

HIV - CMIA Test is Recommended for Individuals:

• Individuals undergoing routine HIV screening
• People who may have had a potential exposure to HIV
• Individuals preparing for certain medical procedures or surgeries, when required
• Pregnant women as part of recommended antenatal screening
• Individuals undergoing sexual health or STI screening
• People with risk factors for HIV infection
• Individuals who want to know their HIV status as part of preventive healthcare

FAQs

1. What does the HIV CMIA test detect?
Depending on the specific assay, it detects HIV antibodies and/or the p24 antigen in blood. It is primarily used as a screening test for HIV infection.

2. Does a reactive HIV CMIA result mean I have HIV?
Not necessarily. A reactive CMIA result is a screening result and requires appropriate confirmatory or supplemental testing before an HIV diagnosis is made.

3. How soon after exposure can HIV CMIA detect infection?
Detection depends on the specific assay and the time since exposure. Fourth-generation antigen/antibody tests can generally detect HIV earlier than antibody-only tests, but no test detects HIV immediately after infection. If exposure was recent, a healthcare provider can recommend the appropriate test and timing for repeat testing.
