Alpha 1 antitrypsin fecal clearance panel - Serum or Plasma and Stool   93419-0

LOINC Code


LOINC code93419-0
nameAlpha 1 antitrypsin fecal clearance panel - Serum or Plasma and Stool
descriptionAn alpha-1-antitrypsin (A1AT or abbreviated as A1A) clearance profile includes results for A1AT levels in serum and 24 hour stool specimen (otherwise 48 or 72 hours, depending on time it takes to collect a stool specimen), as well as the overall A1AT clearance result. Testing is performed to diagnose protein-losing enteropathies. Elevated A1AT clearance (above 50 mL/24 hours) suggests excessive gastrointestinal protein loss.

componentAlpha 1 antitrypsin fecal clearance panel
property-
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+Stool
    Ser  =  Serum
    Plas  =  Plasma
    Stool  =  Stool = Fecal
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
