Alternate Collection Container:
3.5 mL gold-top (serum separator) tube
3 mL green/yellow-top (plasma separator) tube
Specimen required:
Minimum 2.0 mL serum or plasma; minimum 1 mL.

TEST DETAILS
Reference interval:
Negative.
Cutoff concentration ethylene glycol: 10 mg/dL
Additional information:
For 5% of patients with history of chronic alcohol consumption, elevated result between 10 and 35 mg/dL may be expected due to high concentration of 2,3-butanediol. Propylene glycol is a known compound that interferes with this assay. Laboratory will notify the ordering provider if propylene glycol interference is suspected.
CPT code(s):
82693

Test includes:
Serum ethylene glycol.
Methodology:
Enzymatic
Synonyms:
ETHGLY
Clinical significance:
Ethylene glycol screen is used to evaluate and monitor ethylene glycol toxicity. Ingestion of ethylene glycol can result in central nervous system depression (0.5-12 hrs. post ingestion), cardiopulmonary compromise (12-36 hrs. post ingestion) and renal insufficiency (24-72 hrs. post ingestion) from toxic metabolites.
