LOINC code74859-0
nameEthanol [Mass/volume] in Blood Estimated from serum or plasma level
descriptionAlcohol whole blood equivalent is estimated from the serum or plasma level and reported as a percent. The alcohol level in serum or plasma is usually 1.09 to 1.18 times higher than that in whole blood because the cellular component of whole blood dilutes the concentration. [http://www.clinlabnavigator.com/alcohol-ethanol-ethyl-alcohol.html, accessed 20190923] Conversion factors for estimated blood level from serum or plasma level range from 1.10-1.20, and different states or countries may have different legally accepted conversion factors.

componentEthanol
propertyMCnc  =  Mass 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.
systemBld  =  Whole blood
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
