Drugs
of Abuse Analysis (DAU)
The Drugs of Abuse (DAU) screen is a valuable tool for
determining the presence or absence of drugs, or if drugs are used in an abusive manner.
The DAU is also classified as DEA Controlled Substances. See DAU list below. Additionally,
it is the most common screen for employment/pre-employment, quick screen for suspected
drug use, post accidents, and to some extent overdose case. This Excludes Legal
Urine Drugs of Abuse Screens.
