LOINC Code 79716-7: CYP2C9 gene product metabolic activity interpretation Molgen Ql (Bld/Tiss) [Interp]

79716-7 is a LOINC code used to identify CYP2C9 gene product metabolic activity interpretation Molgen Ql (Bld/Tiss) [Interp] 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 CYP2C9 gene product metabolic activity interpretation. It is commonly used with the system or sample type Bld/Tiss.

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 CYP2C9 gene product metabolic activity interpretation. 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

CYP2C9 gene product metabolic activity interpretation in Blood or Tissue Qualitative by Molecular genetics method
CYP2C9 gene product metabolic activity interpretation
The CYP2C9 gene product metabolic activity interpretation is determined by the reporting lab and returned with the structured test results. The Preferred Answer list associated with this term is based on the Clinical Pharmacogenetics Implementation Consortium (CPIC) guidelines for reporting CYP2C9 gene product metabolic activity (phenotype), which apply to both genetic and enzymatic assays (this LOINC term represents a genetic assay). This specific interpretation would be considered a separate observation made by the lab in addition to the primary reported results (e.g., genotype or measured activity level) and it could be included with other assay-specific observations, which would ideally support the interpretation value.
