| Test Name: |
ETHYLENE GLYCOL - (P)
Test Code:
EGOL
|
||||
| Clinical Information: |
Test performed at: St Boniface Hospital by Shared Health Clinical Biochemistry Laboratory using a gas chromatography (GC-FID) method. This is a laboratory developed test.
Ethylene glycol is ordered separately since it is not automatically detected in a screen for alcohols (ethanol, methanol and isopropanol). Volatile Screen is a separate test; on initial screen, lab will add Volatile Screen to the order. Windshield washer antifreeze contains methanol and radiator antifreeze contains ethylene glycol. Propylene glycol will be reported in the ethylene glycol analysis. |

| Specimen Required: |
Plasma: 0.3 mL
Serum collected without gel is also acceptable. Specimen Stability: Refrigerated: 7 days Frozen: 28 days

| More Information: |
Do both ethylene glycol and volatile screens on the initial specimen. If an ingestion is confirmed, subsequent analysis of ethylene glycol or methanol during treatment at approximately 4-6 hour intervals is appropriate.
