LOINC display name : TRBV27 gene segment/TRBV gene segments.total (Bld);
LOINC long common name : TRBV27 gene segment/TRBV gene segments.total in Blood;
LOINC short name : TRBV27 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 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%.;
