This a series of liquid controls intended for use in the forensic/toxicology laboratory. It is used to monitor the performance of the seven chemical pads of urine adulterants in creatinine, nitrite, glutaraldehyde, pH, specific gravity, bleach and pyridinium chlorochromate.

In Drugs of Abuse (DAU) screening, the integrity of the result depends on the validity of the urine samples. It is important to insure that the samples are intact and not adulterated prior to DAU testing.

• DUC-111 is a series of five water-based controls to provide an assessment on the performance of Urine Adulterants:

•  
• Control A for normal conditions
• Control B for Glutaraldehyde and Nitrite positive conditions
• Control C for abnormal Creatinine and Specific Gravity conditions
• Control D for Bleach positive condition
• Control E for pH and Pyridinium Chlorochromate positive conditionns
