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 Measles virus Ab.IgG. It is commonly used with the system or sample type Body fld.

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

What it does not mean

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

Key facts

  • Measles virus IgG Ab [Units/volume] in Body fluid by Immunoassay
  • Measles virus Ab.IgG
  • Quantitative analysis of measles virus IgG antibodies in body fluid by immunoassay-based methods to aid in the diagnosis of recent or current infection. This term is based on, but not limited in use to, the Trinity Biotech Captia (TM) Measles IgG Enzyme-linked Immunosorbent Assay (ELISA), which is detects and quantifies IgG antibodies to measles (Rubeola) virus in human serum for the determination of immune status.
