Transdermal Alcohol Testing and Insensible Perspiration

Alcohol is eliminated from the body by two mechanisms: metabolism and excretion. Metabolism accounts for greater than 90% of ingested alcohol and occurs principally in the liver. The remaining 10% of ingested alcohol is excreted, unchanged, wherever water is removed from the body—breath, urine, perspiration, and saliva. The excreted alcohol is significant because it can be measured and correlated to a person’s Blood Alcohol Concentration. How does the ankle measure alcohol consumption? See how!

SCRAM is the first technology to utilize the science of Transdermal Alcohol Testing in order to monitor for alcohol consumption. Insensible Perspiration is the constant, unnoticeable excretion of sweat through the skin, and the average person will emit approximately one liter of Insensible Perspiration each day. SCRAM measures the ethanol in this Insensible Perspiration - a byproduct of alcohol consumption—in order to determine compliance with required sobriety.

SCRAM’s transdermal testing system is built on a strong scientific foundation supporting the use of transdermal testing in order to determine alcohol consumption. Independent scientists around the United States have researched and correlated TAC results with conventional blood alcohol tests.
