ETHYLENE GLYCOL |
||
Geisinger Epic Procedure Code: LAB2246
Geisinger Epic ID: 54549
|
||
SPECIMEN COLLECTION |
||
Specimen type: |
Serum or plasma. | |
Preferred collection container: |
||
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. | |
| SPECIMEN PROCESSING |
||
Specimen processing instructions: |
Allow to serum clot. Centrifuge to separate serum or plasma within 2 hours of collection. Remove serum from cells. | |
Transport temperature: |
Refrigerated (preferred) or room temperature. | |
Specimen stability: |
Room temperature or refrigerated: 3 days. | |
Rejection criteria: |
Stability limits exceeded. | |
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. | |
