Hi,I am Dr. Shanthi.E (General & Family Physician). I will be looking into your question and guiding you through the process. Please write your question below.
I have been sober for over 14 months and recently took a UA that showed etg levels of just slightly over 5500ng. I have not had a drop of alcohol, use non-alcoholic mouthwash, don't use hand sanitizer, nor have I ingested any cough medicines. What could cause this false positive?
