The need for fast and accurate detection of dermatomycosis.

Dermatomycosis of the hair, skin or nails are one of the most common fungal infection worldwide. Beyond permanent damage to the affected area, the risk of severe dermatomycosis in immunocompromised people can be life-threatening. The potential risk of delayed or improper treatment highlights the need for a rapid and accurate diagnosis. However, with traditional methods of fungal diagnostics such as culture, a diagnosis can take several weeks. Alternative diagnostic technologies have been developed which allow for an appropriate and timely selection of an antifungal treatment, preventing nonspecific over-the-counter self-medication. Such techniques include molecular methods such as PCR, real-time PCR, DNA microarray, next-generation sequencing, in addition to matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) mass spectrometry. Molecular methods can help close the 'diagnostic gap' observed with traditional cultures and microscopy and allow for a rapid detection of dermatomycosis with increased sensitivity and specificity.
