Ethanol in whole blood by detector MS-headspace (code GC73010) – 100 tests package.
INSIGHTS
Ethyl alcohol is an aliphatic alcohol PM=46,07. Usually, it is quickly absorbed through the stomach, small intestine and colon. The time necessary to complete the process of absorption is from 2 to 6 hours and varies as a result of different factors such as the presence of food and other liquids. It has been demonstrated that the maximum concentration is achieved approximately 20 minutes from consumption in blood, saliva and expired air, while in urine the maximum concentration is achieved after approximately two hours. The excessive consumption of alcohol provokes, in the short term, clinical situations of varied gravity that could require medical intervention, both for the direct effects of drunkenness and for indirect ones (eg. car accidents). The doctor could apply to the Laboratory for different reasons such as :
– to assess a possible cause of coma, in patient without cranial trauma;
– to assess the cause of coma in patient with trauma cranial (eg. as a result of a car accident);
– to diagnose drunkenness in patient with doubtful symptomatology.
Small doses of ethanol generally produce euphoria and relaxation; people experiencing these symptoms tend to become talkative and less inhibited, and may exhibit poor judgment. At higher doses ethanol acts as a central nervous system depressant. It also impairs sensory and motor function, cognition. It causes unconsciousness, and possible death.
Principle of the Method:
The sample is transferred into vials for headspace, diluted and added of internal standard. Is then analyzed by GC/FID or GC/MS-headspace.
