Bilirubin.total/Total in Stone by Infrared spectroscopy   74434-2

LOINC Code


LOINC code74434-2
nameBilirubin.total/Total in Stone by Infrared spectroscopy
descriptionEvaluation of bilirubin in gallstones by infared spectroscopy (IRS) is performed to determine the type of gallstone (e.g. cholesterol tone, mixed stone, or pigment stone) and for diagnostic purposes.
statusACTIVE

Fully-Specified Name

componentBilirubin/Total
propertyMFr  =  Mass Fraction
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.
systemCalculus  =  Calculus (=Stone)
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
methodInfrared spectroscopy
