LaboratoryEthanol [Mass/volume] in Blood Estimated from serum or plasma level
Definition
Alcohol 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.
