To prepare for a Urine Cotinine test, there are a few steps you can take. Firstly, if you are a smoker, try to abstain from smoking for as long as possible before the test. Cotinine, a metabolite of nicotine, can remain in your body for several days, so quitting or reducing smoking in advance can help lower cotinine levels. Additionally, staying hydrated by drinking plenty of water can dilute the concentration of cotinine in your urine. Lastly, it's essential to follow any specific instructions provided by the testing facility, such as avoiding certain foods or medications.
