Zinc Sulfate, a Recently Introduced Urinary Adulterant Can Invalidate Urine Cotinine Test Using Immunoassay but Has Less Effect on Liquid Chromatography Combined With Tandem Mass Spectrometry–Based Test

Zinc sulfate caused false-negative cotinine result when DRI immunoassay was used and also had small to moderate impact on liquid chromatography combined with tandem mass spectrometry–based assay for urine cotinines.

HOW TO BEAT A DRUG TEST The Anti-Kickback Dragnet

Further research concerning the detection of oxidation products of THC-COOH following urinary adulteration

The primary goals of this research are to assess the efficacy of a range of adulterants on the detection of THC-COOH in vitro, and to ascertain whether novel reaction products specific to the reaction of cannabinoid, Δ-tetrahydrocannabinol, with selected adulterant form can act as markers of both cannabis use and urine adulteration.

Bioanalysis of urine samples after manipulation by oxidizing chemicals: technical considerations.

The effect of various popular oxidizing adulterants on urine drug test results, the countermeasures taken by laboratories in dealing with adulterated urine samples and the prospect of developing more robust and economical methods to combat urine adulteration in the future are described.
