title: A procedure for the detection of Stealth adulterant in urine samples.
abstract: Stealth is an adulterant that is advertised as not only preventing a positive drug test in urine, but also to be undetectable by currently available adulteration testing. It has previously been described as a peroxidase and peroxide that is added to urine for the sole purpose of preventing a positive drug test. The product was found to have a significant impact on the ability to detect several drugs of abuse, however, detecting the presence of the adulterant in urine had not yet been reported. A simple procedure to detect the presence of this adulterant in urine was developed. This simple color test procedure using commercially available reagents commonly used in clinical laboratories is based on the use of a chromogen to detect the peroxidase reaction in urine samples. If Stealth is present in the urine, the test sample will show an immediate color change from clear to dark brown. This qualitative test can also be adapted for use with a spectrophotometer or autoanalyzer.
