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 Precision of boundaries. It is commonly used with the system or sample type ^Patient.

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: TRIAL
  • Order vs observation: Observation

What it does not mean

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

Key facts

Precision of boundaries Nominal
Precision of boundaries
The precision of the nucleotide boundaries that can be specified for a structural variant can vary widely, and in some cases the boundary can only be pinpointed down to a region that is on the order of megabases. This term should be used to report the narrative description of the boundary precision. The nucleotide ranges for the narrowest and widest possible boundaries of a structural variant can be reported using [LOINC81302-2] and [LOINC: 81301-4], respectively.
