A member asked:
Very good evening doctors. can you drink water and use toothpaste and/or mouthwash before a fasting glucose and cholesterol blood test?
A doctor has provided 1 answer
There should be no issues using toothpaste or mouthwash before a blood test. You are not swallowing the products, and they do not contain any sugar.
