Although there are only a small handful of products that can be used to change the result of an impending test, there are validity screens available which can detect these adulterants. Some are integrated into the tests, such as the iCup®, which has built-in adulteration available, and we also have individual adulteration strips.
Are there products that can be used in the tests to give a false negative? What can be done to avoid this?
