About this service

Blood Alcohol (Ethanol) by HSGC-FID analysis is a laboratory test designed to measure the concentration of ethanol in the blood. This analysis is commonly used to assess the level of alcohol intoxication, whether in medical settings such as emergency care or in legal contexts such as cases of driving under the influence of alcohol. The accuracy of the analysis relies on gas chromatography technology, which separates compounds based on their chemical properties, allowing reliable results to be obtained. This test is considered a vital tool for guiding necessary medical treatment or making appropriate legal decisions.

Purpose Test

Ethanol Concentration in Blood: Measures the amount of alcohol in the sample, helping assess the level of alcohol intoxication.
Acute Poisoning Cases: Determines the impact of alcohol on body functions, guiding medical interventions.
Assessment of Risky Behaviors: Such as driving under the influence, with results used for legal purposes.
Patient Monitoring: For individuals receiving addiction treatment or needing monitoring of alcohol levels for medical reasons.

Recommended groups

Individuals suspected of alcohol intoxication: Such as those showing symptoms like loss of consciousness or impaired coordination.
Drivers involved in accidents: The test is used to determine if alcohol contributed to the incident.
Individuals seeking help in addiction treatment programs: To assess alcohol levels before starting treatment.
Patients in emergency situations: Where alcohol may affect treatment plans or surgery.
Employees in safety-sensitive professions: Such as bus drivers or pilots, requiring periodic alcohol level checks.

Symptoms indicative

Loss of consciousness or confusion: Difficulty responding or orienting.
Coordination disturbances: Such as inability to walk properly or control movements.
Behavioral changes: Such as aggression or excessive irritability.
Nausea or vomiting: Especially if accompanied by other symptoms.
Difficulty breathing: Or any respiratory issues that may indicate severe intoxication.
Severe headache: May be associated with consuming large amounts of alcohol.

Normal Levels

For individuals who have not consumed alcohol: The normal blood ethanol level is typically 0 µg/dL or less than 0.01% (10 mg/dL).
Legally acceptable levels: In many countries, blood alcohol levels below 0.08% (80 mg/dL) are considered safe for driving.
