LOINC Code


LOINC code19218-7
nameOxygen content in Arterial blood
descriptionBe very careful about mapping to this term. We cannot confirm that anyone reports it in this manner - perhaps as number of molecules of oxygen in a given volume. We also cannot confirm that there is a method for measuring oxygen content directly (rather than as the calculation given under the term 59274-1). Likewise we cannot prove that such an approach does not exist. However, all of the usages that we know about are based on calculations. So be very careful about mapping to oxygen saturation terms that are not derived from calculations, e.g. this term and LOINCs 34163-6 and 19219-5.

componentOxygen content
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.
systemBldA  =  Blood arterial
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

Associated Observations

LOINC codes that represent optional associated observation(s) for a clinical observation or laboratory test. A LOINC term may represent a single associated observation or panel containing several associated observations.
