Overview-

A real time PCR- based multiplex application for fast, reliable, ready to use and high throughput in vitro diagnostic of dermatophytes. This multiplex PCR system enables 7 different dermatophytes types detection within 3 hours. The test contains two ready to use mixes for detection of 7 most common dermatopytes types:

[ 1 ] Trichophyton tonsurans

[ 2 ] Trichophyton violaceum

[ 3 ] Trichophyton rubrum complex

[ 4 ] Trichophyton mentagrophytes complex

[ 5 ] Microsporum canis

[ 6 ] Microsporum gypseum

[ 7 ] Epidermophyton floccosum

and Internal Control.

Specimen-

This test is for use with extracted DNA from skin scale specimens, plucked

hair, nails, culture and swabs of human origin.

Workflow-

Sample collection-sample lysis in lab-DNA purification manually or automated-add DNA and running Real

time PCR-results automatic analysis.

Clinical validation results-

A total of 220 samples were examined. Acorrelation of 86.3% (190/220) was found between the methods.
