79721-7

LOINC code 79721-7 identifies "CYP4F2 gene product metabolic activity interpretation in Blood or Tissue Qualitative by Molecular genetics method". The CYP4F2 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 CYP4F2 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.

This code measures CYP4F2 gene product metabolic activity interpretation in Bld/Tiss. It belongs to the MOLPATH.PHARMG class in the LOINC classification.

LOINC (Logical Observation Identifiers Names and Codes) is a universal standard for identifying laboratory and clinical observations. It is maintained by the Regenstrief Institute and used worldwide for health data exchange.
