The IntectCheck is 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 Intect 7, 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.
