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 Variable nucleotide. It is commonly used with the system or sample type Bld/Tiss.

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: Observation
  • Method: Molgen

What it does not mean

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

Key facts

  • Genomic alt allele [ID]
  • Variable nucleotide
  • The genomic alternate allele is the contiguous segment of DNA in the test sample that differs from the reference allele at the same location and thus defines a variant.
