2,3-Butanediol was mistakenly identified as ethylene glycol in plasma specimens from two alcoholic patients. The cyclic phenylboronate ester derivatives of 2,3-butanediol and ethylene glycol had the same retention time when OV-17 was used as the stationary phase for gas chromatography. This led to incorrect diagnosis of ethylene glycol poisoning and unnecessary invasive therapy. Plasma from two chronic alcoholics contained 2,3-butanediol at 3.5 and 3.4 mmol/L. The elimination half-life of 2,3-butanediol was 3.9 days when ethanol was administered during therapy for suspected ethylene glycol poisoning. Low concentrations of 2,3-butanediol might be present in blood of chronic alcoholics as a result of a novel pathway of intermediary metabolism associated with some forms of alcoholism. However, a more likely explanation for fairly high concentrations of 2,3-butanediol is enzymatic production from 2-butanone. This ketone occurs in denatured alcohol preparations often consumed by alcoholics in Sweden.
