We can test breath, saliva or urine to determine alcohol use.  The most effective instrument to determine impairment is an evidentiary breath alcohol test.  Our device tests and confirms the presence, impairment and use of alcohol.

Our laboratory can show use several days in the past through an ETG test.  However, the ETG does not show impairment.  this is good for a person who is court ordered not to consume alcoholic beverages or a person on a contract for such.
