What blood test are for cotinine?

Cotinine is typically measured through a blood test specifically designed to detect nicotine and its metabolites. The most common test is the cotinine blood test, which can determine recent tobacco use. It is often used in clinical settings to assess exposure to nicotine, especially in individuals who may be trying to quit smoking or in research studies related to tobacco use. Other testing methods include urine and saliva tests, but the blood test is considered more accurate for measuring cotinine levels.
