| description | This assay represents the fraction of T-cell receptor beta chain variable gene segments that are in the TRBV12 gene family out of the total number of TRBV gene segments identified ("diversity ratio"). At the time this term was created, TRBV12 included the following gene segments: TRBV12-1, TRBV12-2, TRBV12-3, TRVB12-4, and TRVB12-5. 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%. | ||

| property | NFr = Number Fraction | ||
| time | Pt = Point in time: To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements. | ||
| system | Bld = Whole blood | ||
| scale | Qn = Quantitative: The result of the test is a numeric value that relates to a continuous numeric scale. Reported either as an integer, a ratio, a real number, or a range. The test result value may optionally contain a relational operator from the set {<=, <, >, >=}. Valid values for a quantitative test are of the form "7", "-7", "7.4", "-7.4", "7.8912", "0.125", "<10", "<10.15", ">12000", 1-10, 1:256 | ||
