LOINC Code 82482-1: TRBV27 gene segment/TRBV gene segments.total (Bld)

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 TRBV27 gene segment/TRBV gene segments.total. It is commonly used with the system or sample type Bld.

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

What it does not mean

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

Key facts

• TRBV27 gene segment/TRBV gene segments.total in Blood
• TRBV27 gene segment/TRBV gene segments.total
• This assay represents the fraction of T-cell receptor beta chain variable gene segments that are in the TRBV27 gene family out of the total number of TRBV gene segments identified ("diversity ratio"). At the time this term was created, the TRBV27 segment did not contain any subtypes. Because some portion of TRBV gene segments that are counted in the total will not correspond to any of the probes and therefore will not be identified as belonging to a specific TRBV gene family, the total of the diversity ratios reported will not equal 100%.
