Bicarbonate [Moles/volume] standard in Plasma   69964-5

LOINC Code


LOINC code69964-5
nameBicarbonate [Moles/volume] standard in Plasma
descriptionConcentration of bicarbonate in plasma separated anaerobically from whole blood at 38 degree Celsius and equilibrated at a pCO2 of 40 mm Hg with the blood Hb fully saturated with oxygen. It is a measure of the acid-base balance in a sample of blood after the correction of a respiratory disorder. As a result, abnormal values for standard bicarbonate reflect only the metabolic component of an acid-base disturbance. Elevation indicates metabolic alkalosis, while depression indicates metabolic acidosis.

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.
systemPlas  =  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
