Use
The Ethanol, Serum or Plasma test is used to identify acute alcohol ingestion. It helps determine alcohol levels in biological samples for medical purposes, particularly in emergency toxicology assessments. The test is crucial in managing cases of suspected alcohol intoxication and monitoring ethanol levels in patients with alcohol use disorders.
Special Instructions
This test must be arranged considering the timing of exposure and should be conducted upon the patient's presentation to the hospital. Use a nonalcohol-based cleanser at the venipuncture site to avoid contamination when drawing blood for alcohol testing.
