Certified Drug Free Urine (Liquid)

UTAK's Certified Drug Free Urine (Liquid) is 100% real human urine collected from healthy donors within the United States. As part of our donor qualification process, specimens are screened and confirmed negative for the following analytes: d-Amphetamine, d-Methamphetamine, Benzoylecgonine (BE), (-)-Cotinine, Morphine, Oxazepam, and (l)-9-Carboxy-11-nor-Delta-9-THC (THC-COOH). Residual analyte concentrations are not characterized or certified for diagnostic use. This material contains Sodium Azide as a preservative and is suitable for use as a raw material component in the preparation of standards, controls, and calibrators, and for general laboratory applications including method development and validation. Commonly used in workflows involving LCMS, LC-MS/MS, GCMS, Time of Flight (TOF), ELISA, EMIT, and other immunoassays. Users must qualify and validate this material for their specific application and instrumentation prior to use. Not for diagnostic use or direct administration to humans.
