Test Overview
Test Methodology

Gas Chromatography (GC)

Test Usage

Evaluate methanol and isopropanol toxicity, alcohol (ethanol) drug abuse, and ethylene glycol toxicity. Acetone is a metabolite of isopropanol and may be elevated in cases of acute isopropanol ingestion. In diabetic ketoacidosis acetone can also be found in serum concentrations up to 70 mg/dL.

Reference Range *

Normal Ranges: None present
Toxic ranges:
Ethanol > 450 mg/dL
Isopropanol > 340 mg/dL
Methanol > 20 mg/dL
Acetone > 20 mg/dL
Ethylene Glycol > 30 mg/dL

STAT Availability

STAT requests for this test will be performed on a STAT basis (supervisory staff approval is not required).

Specimen Requirements
Collection Instructions

Collect blood in green top tube. Do not remove stopper from collection tube. Refrigerate and send intact specimen. Gray top (sodium fluoride/potassium oxalate), Red top, SST top, or Lavender top tubes are also acceptable. Other specimen types: Collect or place in clean plastic container, close tightly, and refrigerate. Assay can be performed on whole blood, serum, plasma, gastric washings, or vitreous humor.

Alternate Specimen
Gray top, red top, SST, lavender top (EDTA). [rev 11/09] Plasma is the preferred specimen type for this assay.
Normal Volume
1 mL serum or plasma
Minimum Volume
0.5 mL serum or plasma
Additional Information

Test includes quantitation of Ethanol, Methanol, Isopropanol, Ethylene Glycol, and Acetone. For ethanol level only, see Ethanol.
