Confirming and monitoring ethylene glycol toxicity
1. Centrifuge and aliquot serum into plastic transfer tube within 2 hours of collection.
Please follow the STAT Ethylene Glycol and Volatiles procedure in DCS for handling and transportation of the sample(s) to Mayo Clinic Laboratories.
*This test is only valid to be ordered from MCHS hospital location/branches which includes the following branches: MMC-Marshfield, MMC-Eau Claire, MMC-Park Falls, MMC-Ladysmith, MMC-Minocqua, MMC-Neillsville, MMC-Rice Lake, MMC-Weston
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.
Toxic concentrations greater than or equal to 20 mg/dL
