LOINC Code 75666-8: HIV 1+2 Ab and HIV1 p24 Ag IA.rapid Nom (S/P/Bld)

What is this code?

LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component HIV 1+2 Ab & HIV1 p24 Ag. It is commonly used with the system or sample type Ser/Plas/Bld.

When is it used?

• Used in lab systems, EHRs, and clinical data exchange.
• May identify a test, observation, survey item, or clinical document request rather than a diagnosis.
• Status: ACTIVE
• Order vs observation: Both
• Method: IA.rapid

What it does not mean

• The code identifies the observation or test, not the actual result.

Key facts

• HIV 1+2 Ab and HIV1 p24 Ag [Identifier] in Serum, Plasma or Blood by Rapid immunoassay
• HIV 1+2 Ab & HIV1 p24 Ag
• Simultaneously and separately detects HIV-1 p24 antigen (Ag) and HIV-1/2 antibodies (Ab) in human serum, plasma, capillary, and whole blood. Detecting both HIV-1/2 antibodies and the HIV-1 antigen allows earlier diagnosis of HIV than tests relying solely on the presence of HIV 1/2 antibodies because the antigen may be detectable before the virus. This assay is not intended for newborn screening, cord blood specimens, or on individuals less than 12-years. It is also not intended for use in screening blood products or tissue donors. This term was based on, but not limited in use to, the Alere Determine HIV-1&2 Ag/Ab Combo test kit, which delivers results in 25-30 minutes.
