Total thyroxine binding capacity in Serum or Plasma   74795-6

LOINC Code


LOINC code74795-6
nameTotal thyroxine binding capacity in Serum or Plasma
descriptionT-uptake in T uptake units. T uptake units bear a rough INVERSE relationship to the other T uptake (See AxSym package insert: http://www.promtest.am/tests/thyroid-diagn/T-Uptake.pdf), but actually measures a different phenomenon (total binding capacity instead of unbound hormone).
statusACTIVE

Fully-Specified Name

componentTotal thyroxine binding capacity
propertyRelRto  =  Relative Ratio
timePt  =  Point in time:  To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements.
systemSer/Plas
    Ser  =  Serum
    Plas  =  Plasma
scaleQn  =  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
