The Cozart Bioscience EIA Cotinine Urine Kit is intended for laboratory based testing in clinical and analytical laboratories and for insurance assessment. It provides qualitative screening results for Cotinine in human urine at a cut-off concentration of 500ng/mL. The Cozart EIA Cotinine Urine Kit acts as an aid in the detection of cotinine after use of tobacco products or other products containing nicotine.
This assay is for professional use only and provides only a preliminary analytical test result. Clinical consideration and professional judgement must be applied to any drug of abuse test result, particularly in evaluating a preliminary positive result. In order to obtain a more confirmed analytical result a more specific alternative chemical method is needed. Gas Chromatography/Mass Spectrometry (GC/MS) is the preferred confirmatory method.
Indications for use as stated in the FDA summary.
