[Requirements for mycological diagnostics in accordance with the guideline of the German Medical Association for quality assurance of medical laboratory tests].

The ability of recognizing various clinical manifestations of mucocutaneous mycosis, making a diagnosis, and establishing a treatment is part of a dermatologist's daily routine. However, due to the fact that clinical manifestations, laboratory diagnostics, and treatment are performed in one hand, laboratory findings are properly classified and interpreted. Since new binding guidelines of the German Medical Association on quality assurance measures in medical laboratory testing came into force, there is much concern among dermatologists of how to comply with these new regulations. It is the intention of the authors to help our readers to implement these new rules in order to make sure that mycological diagnostics continue to be part of a dermatologist's professional work.
