Ethylene Glycol Mass Concentration (Serum/Plasma)

Why Is This Test Done?

Your healthcare provider may order this test if you’ve been exposed to ethylene glycol (e.g., through ingestion of antifreeze, certain medications, or contaminated products). Symptoms of poisoning can include nausea, vomiting, confusion, seizures, or kidney failure. This test helps confirm exposure and guides treatment decisions.

What to Expect Before the Test

No special preparation is needed. You’ll provide a blood sample (usually from a vein in your arm) or, in some cases, urine. The test is quick and painless, though you may feel slight discomfort from the needle insertion.

What to Expect After the Test

After the blood draw, you may experience mild bruising, swelling, or soreness at the site. Apply a cold compress if needed. Avoid heavy lifting or strenuous activity for a few hours. If you experience unusual symptoms (e.g., dizziness, severe pain), contact your provider.

What the Results Mean

High levels of ethylene glycol in your blood can indicate poisoning. Very low or undetectable levels suggest no recent exposure. Your results will be compared to clinical judgment and symptoms to determine next steps, such as treatment or monitoring.
