Many drug users will attempt to evade detection by adulterating the specimen in order to produce false negative results during the initial immunoassay screening. Adulteration methods include dilution with water, substitution with a drug free liquid, addition of readily available household materials (e.g., vinegar, baking soda, liquid drain opener, detergent, etc.) or tampering with certain chemicals (e.g., Urine-Aid, which contains glutaraldehyde or Klear, which contains potassium nitrite). Several oxidizing adulterants are being sold with a claim to clear all positive drug test results. The most commonly used oxidizing adulterants are Nitrite (Klear(TM)), Chromate (Urine Luck(TM), Iodine, Bleach and Horse Radish peroxidase/H202 Stealth(TM)). When added to urine, there is no significant change to the appearance, pH, specific gravity or creatinine concentration. Marijuana samples adulterated with oxidants can produce a positive result, during initial screening by immunoassay, notably the marijuana metabolite (THC). However, they can not be confirmed by GC/MS. This method is designed to detect these oxidizing adulterants.

After voided midstream collection is complete, mix the specimen and
transfer a 10 mL aliquot of urine to a transfer tube with a
screw cap closed tightly to avoid leakage. Transfer tubes are
available from Client Supply. Refrigerated specimens are preferred
(store at 2-8 degrees C). Ship refrigerated.
