LOINC display name : TRBV18 gene segments/TRBV gene segments.total (Bld);
LOINC long common name : TRBV18 gene segments/TRBV gene segments.total in Blood;
LOINC short name : TRBV18 seg/TRBV seg total NFr Bld;
LOINC description : This assay represents the fraction of T-cell receptor beta chain variable gene segments
that are in the TRBV18 gene family out of the total number of TRBV gene segments identified
(diversity ratio). At the time this term was created, TRBV18 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%.;
