Interference

Propionic acid produced in the rare inborn error of metabolism methylmalonic acidemia may be confused with ethylene glycol in the gas chromatographic assay.

Specimens collected in serum gel tubes are not acceptable, as the drug/analyte can absorb on the gel and lead to falsely decreased concentrations.
