nameTestosterone Free [Moles/volume] in Serum or Plasma by calculation
descriptionFree testosterone calculated based on the measured values for testosterone, sex hormone binding globulin (SHBG), and albumin, depending on the equation used. The Nanjee-Wheeler and Ly-Handelsman equations use testosterone and SHBG, and Sodergard and Vermeulen equations use testosterone, SHBG, and albumin to calculate the free testosterone.

propertySCnc  =  Substance 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
