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.
