Why This Test Matters

Ethylene glycol poisoning is a medical emergency. This test helps doctors assess exposure by measuring the toxic substance in your urine. It’s often used when someone has ingested antifreeze or similar chemicals, especially if symptoms like confusion, vomiting, or seizures appear.

What to Expect During Testing

You’ll provide a urine sample, typically collected in a clean container. The lab uses a sensitive method to detect ethylene glycol levels. Results help determine if treatment is needed, such as antidote administration or kidney support.

Possible Causes of Abnormal Results

Elevated levels may result from accidental or intentional ingestion of ethylene glycol-containing products (e.g., antifreeze, windshield deicer). Symptoms like dizziness, rapid breathing, or kidney damage can occur. Chronic exposure may also lead to long-term health risks.

Symptoms That May Trigger This Test

Your healthcare provider may order this test if you’ve experienced symptoms like nausea, vomiting, confusion, or seizures—especially after exposure to antifreeze or similar chemicals. It’s also used in cases of suspected poisoning or when monitoring someone with known exposure.
