Alcohol (Ethanol C2H5Oh)
|Background:||The most important need for ethanol measurement, clinically, is in the identification of acute intoxification, particularly in differential diagnosis of unexplained coma, and monitoring chronic alcohol abuse. Ethanol measurement is also important in blood and urine for post mortem samples*
Urgent analysis for alcohol toxicity may be required, particularly in the young.
Ethanol is also used to treat Ethylene Glycol (antifreeze) or methanol poisoning through competitive inhibition of the metabolic pathway and measurements of the dosage will be required.
