80203-3 is a LOINC code used to identify HIV 1 and 2 Ab IA.rapid Nom (S/P/Bld) in laboratory and clinical observation data. You may see this code in lab systems, lab reports, EHR exports, interoperability feeds, or other structured clinical data exchanges. 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.

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. 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 and 2 Ab [Identifier] in Serum, Plasma or Blood by Rapid immunoassay
HIV 1 & 2 Ab
This assay detects and differentiates between six distinct HIV antibodiesHIV-1 gp160, gp41, p31, and p24 and HIV-2 gp140 and gp36. It is intended for use as an additional, more specific test to confirm the presence of HIV-1 and HIV-2 antibodies found by screening procedures. It may also be used to confirm the presence of antibodies to HIV-1 and HIV-2 in pediatric subjects (children as young as 2 years of age). Because this assay examines antibodies to 6 distinct proteins, it yields a higher degree of specificity for HIV-1 and -2 compared to other methods (such as Multispot). This term was created for, but not limited in use to, the submitter's Bio-Rad Geenius HIV 1/2 Supplemental test kit.
