Accutest Oral Fluid Cotinine Test Mini Cube (DS443)

The Accutest Saliva Cotinine Test is a rapid, screening test for the simultaneous, qualitative detection of Cotinine in human oral fluid.

Product Description

The Accutest Saliva Cotinine Test is a lateral flow chromatographic immunoassay for the qualitative detection of cotinine in oral fluids at a cut-off concentrations of 30 ng/mL.

The Accutest Saliva Cotinine Test is a rapid, oral fluid screening test that can be performed without the use of an instrument. The test utilizes antibodies to selectively detect elevated levels of specific drugs in human oral fluid.

Cotinine is the first-stage metabolite of nicotine, a toxic alkaloid that stimulates the autonomic ganglia and central nervous system in humans. Nicotine is a drug to which virtually every member of a tobacco-smoking society is exposed whether through direct contact or second-hand inhalation. Aside from tobacco, nicotine is also commercially available as the active ingredient in smoking replacement therapies such as nicotine gum, transdermal patches and nasal sprays.

Regardless of whether nicotine in a donor was derived from tobacco use or through a nicotine-replacement therapy, if the metabolite cotinine is present in sufficient concentration, the test result will be positive.

Although nicotine is excreted in saliva, the relatively short half-life of the drug makes it an unreliable marker for tobacco use.

Cotinine, however, demonstrates a substantially longer half-life than nicotine, bears a high correlation with plasma cotinine levels and has been found to be the best marker for smoking status compared with saliva nicotine measurements, breath carbon monoxide testing and plasma thiocyanate testing.

The window of detection for cotinine in saliva at a cutoff level of 30 ng/mL is expected to be up to 1-4 days after nicotine use.
