Note: The EP/BP criteria requires a reduction of bacteria at 2 days, this is the most stringent criteria for bacteria. The CTFA criteria requires a reduction of fungi at day 7, this is the most stringent criteria for fungi.
 The CTFA test allows the microorganisms to be pooled into groups of bacteria, fungi and mold. Additional organisms are listed in the procedure. In addition, at least one rechallenge is recommended for an additional 28 days.
 The acceptance criteria listed above is only for topical products. The criteria will differ for other categories.
 The EP/BP A criteria express the recommended efficacy to be achieved. In justified cases where the A criteria cannot be attained, for example, for reasons of an increased risk of adverse reactions, the B criteria must be satisfied.
