What the Test Measures

This test measures the level of cotinine in your blood, which reflects recent exposure to nicotine. Cotinine remains in the bloodstream longer than nicotine, making it a more accurate marker of tobacco use. It helps identify active smokers, passive exposure to tobacco smoke, and the effectiveness of smoking cessation efforts.
