Comments:

No therapeutic range
• Assay detection limit 5 mg/dL
Potentially toxic: Greater than 20 mg/dL.
Toxic concentrations may cause intoxication, CNS depression, metabolic acidosis, renal damage and hypocalcemia. Ethylene glycol is extremely toxic. Ingestion can be fatal if patients do not receive immediate medical treatment.
