is green‚ when an alcohol is oxidized by the reagent. A change in color of the reagent from orange to green represents a positive test.

Abstract Alcohol consumption may be linked to syncopal events. The mechanism by which alcohol may induce syncope is not well understood.

These findings have implications for understanding of hemodynamic effects of alcohol and‚ in particular‚ for understanding
