nameInulin renal clearance/1.73 sq M in Urine and Serum or Plasma
descriptionInulin is measured to evaluate kidney function by determining the glomerular filtration rate (GFR) -- the flow rate of filtered fluid through the kidney. Inulin is completely filtered at the glomerulus, allowing the clearance of inulin to be used as a highly accurate measure of GFR. The submitter laboratory's testing approach is to collect samples every 30 minutes up to 240 minutes after an 18 hour infusion with inulin (long test) or after an initial bolus injection (short test).

propertyArVRat  =  Volume Rate/Area
timeStdy  =  Duration of the study
systemUrine+Ser/Plas
    Ser  =  Serum

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
