Clinistix and Diastix are approved for testing for the presence of glucose in the urine. The below tip is an off-label use of these glucose testing methods.
Want to make sure that Diet Coke is actually diet? Use Clinistix or Diastix urine glucose test strips to test. Just take a small amount of food or drink in your mouth and mix it with your saliva, then spit out a small amount on the test strip. A change in color indicates the presence of sugar or starch. Don’t just dip the test strip into the food or drink; saliva is essential to the reaction because it contains an enzyme that releases glucose.
