Cotinine test (nicotine test)

Detects use of nicotine products.
 
This test measures the amount of cotinine in your urine. Cotinine is a chemical your body makes after you are exposed to nicotine. Measuring cotinine is better than measuring nicotine because nicotine disappears from your system within a few hours, but cotinine remains for a day or more. May be required as a pre-op lab test.
