title: Misidentification of propionic acid as ethylene glycol in a patient with methylmalonic acidemia.
abstract: Reexamination of serum from a child thought to have died of ethylene glycol poisoning showed that the child had methylmalonic acidemia. The gas chromatographic peak identified as ethylene glycol by a clinical laboratory was actually due to propionic acid. Proof of a metabolic basis for the child's symptoms eventually exonerated his mother of the charge of murder.
