What does this LOINC code represent?

This LOINC code identifies a lab observation, measurement, question, or clinical concept in a standardized format.

Is this enough to understand my test result?

No. The code identifies the test or observation, but the interpretation depends on the actual result, reference range, and clinical context.

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 UGT1A1 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

UGT1A1 gene product metabolic activity interpretation in Blood or Tissue Qualitative by Molecular genetics method

UGT1A1 gene product metabolic activity interpretation

The UGT1A1 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 UGT1A1 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.
