Why Is This Test Done?

Your healthcare provider may order this test if you’ve ingested antifreeze, a product containing ethylene glycol, or if you have symptoms like confusion, vomiting, or difficulty breathing. It’s also used in cases of suspected poisoning or unexplained metabolic issues.

What to Expect During the Test

A blood sample will be taken from a vein in your arm. You may feel a slight pinch, but it’s usually over quickly. The sample is sent to a lab for analysis using a specialized method to detect ethylene glycol levels accurately.

Possible Symptoms of Ethylene Glycol Poisoning

Ethylene glycol poisoning can cause symptoms within hours of exposure, including nausea, vomiting, rapid breathing, confusion, seizures, or even coma. If you suspect poisoning, seek emergency care immediately.

What the Results Mean

Results are reported as a mass concentration (typically in mg/dL or mg/L). Very high levels indicate poisoning and require urgent medical treatment, such as dialysis or supportive care. Low or normal levels mean no acute poisoning was detected, but further evaluation may still be needed if symptoms persist.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

What causes high levels of ethylene glycol in the blood?
High levels are most commonly due to accidental or intentional ingestion of antifreeze, antifreeze-based products, or ethylene glycol-containing solvents. Other rare causes include industrial exposure or contamination in medical settings.
How soon after exposure should I get tested?
Ideally, testing should occur within 24 hours of suspected exposure, as ethylene glycol levels rise quickly in the blood. However, even if symptoms appear later, testing may still be necessary to assess risk or guide treatment.
Can ethylene glycol poisoning be treated without medical intervention?
No, ethylene glycol poisoning is a medical emergency. Treatment typically includes fluids, dialysis, or medications to break down the toxin. Delaying care can worsen outcomes, so seek emergency help immediately if poisoning is suspected.
