The cotinine/nicotine one-step test device (urine) is an immunoassay based on the principle of competitive binding. Drugs which may be present in the urine specimen compete against the drug conjugate for binding sites on the antibody. During testing, a urine specimen migrates upward in a lateral flow of chromatographic immunoassay for detection of cotinine in human urine at a cut-off concentration of 200 ng/mL.
