Cotinine Screen, Oral Fluid

This test measures the level of cotinine in your saliva, which is a chemical your body creates after breaking down nicotine. It helps show whether you have recently used tobacco, electronic cigarettes, or nicotine replacement products like patches. This screening helps confirm if nicotine is currently present in your system. However, it cannot identify exactly which specific product you used or diagnose health conditions caused by smoking.
