PTC Taste Test Paper tests for the genetically controlled ability to taste this substance. This will allow for the development of a Pedigree for an individual.
NOTE: The concentration of ingredients is usually so small, it is less than what would be considered hazardous. Aside from these small quantities, cellulose paper is the only other ingredient. In addition, the proper use of each taste test is to touch the strip to the tongue. These taste strips have been used safely in classrooms for decades.
