Marker Test Diagnostics, Inc.
Sample integrity is one of the biggest issues in drug testing. Even under observation, sample adulteration and/or substitution is very common. Eliminate observed collections, false positive/negative results and adulteration with UR Code, the accurate, secure and cost-effective solution from Marker Test Diagnostics. UR Code is an oral marker that internally “bar-codes” a subject’s urine and eliminates the need to supervise urine collection.
