name
descriptionThis term was created for, but is not limited in use to, bioMerieux's VIDAS T3 assay, which is intended for the quantitative measurement of triiodothyronine (T3) in human serum or plasma.
statusACTIVE

Fully-Specified Name

componentTriiodothyronine
propertyMCnc  =  Mass Concentration
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
methodIA  =  Immunoassay:  Encompasses all immunoassays with a few exceptions, including Immune Blot and Immune Fluorescence, which were created based on historic usage.
