Methodology

Chemiluminescent Microparticle Enzyme Immunoassay (CMIA)

Testing Schedule

Routine, daily

Report Availability

2-4 days 

Minimum Volume

2 mL plasma

Container

2 White top tubes, EDTA

Collect

White top (EDTA): Centrifuge for 20 minutes at 800-1600 xg (3000 rpm)
Do not aliquot. Refrigerate.

 

Special Instructions

  • Specimen must be received in the original Vacutainer tube. Aliquot tubes will not be accepted.
  • The Department of Health requires mandatory reporting of any confirmed positive result.

Clinical Utility

This test detects both the HIV antibody and the p24 antigen, thereby decreasing the window period and allowing earlier detection of acute infection with HIV.

Reference Range

Negative
Note: Repeatedly reactive screens will automatically be confirmed by HIV1/HIV-2 differentiation assay and if necessary HIV-1 viral load. These are preliminary until confirmatory test results are available and final interpretation is made. 

Includes

  • HIV-1 and HIV-2 Antibody and HIV-1 p24 Antigen
  • Reflexed when appropriate: 
    • HIV-1/HIV-2 Differentiation assay
    • HIV-1 Viral Load

Clinical Utility
