82498-7
LaboratoryTRBV5 gene segments/TRBV gene segments.total in Blood
Definition
This assay represents the fraction of T-cell receptor beta chain variable gene segments that are in the TRBV5 gene family out of the total number of TRBV gene segments identified ("diversity ratio"). At the time this term was created, TRBV5 contained the following subtypes: TRBV5-1, TRBV5-2, TRBV5-3, TRBV5-4, TRBV5-5, TRBV5-6, TRBV5-7, and TRBV5-8. 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%.

Frequently Asked Questions
What is LOINC code 82498-7?
LOINC code 82498-7 identifies "TRBV5 gene segments/TRBV gene segments.total in Blood". This assay represents the fraction of T-cell receptor beta chain variable gene segments that are in the TRBV5 gene family out of the total number of TRBV gene segments identified ("diversity ratio"). At the time this term was created, TRBV5 contained the following subtypes: TRBV5-1, TRBV5-2, TRBV5-3, TRBV5-4, TRBV5-5, TRBV5-6, TRBV5-7, and TRBV5-8. 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%.
What does 82498-7 measure?
This code measures TRBV5 gene segments/TRBV gene segments.total in Bld. It belongs to the MOLPATH class in the LOINC classification.
What is LOINC?
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.
