InTray® DM

InTray DM is an enriched dermatophyte medium used in the detection of dermatophytes from clinical specimens.

Dermatophytes are fungi in the genera Microsporum, Tricophyton and Epidermophyton. They are capable of metabolizing keratin found in skin, hair and nails of living hosts. The fungi characteristically may invade the cutaneous tissue of the living host but rarely penetrate the subcutaneous tissue. Tinea and ringworm are two terms commonly used to describe dermatophytes. InTray DM is formulated to produce a red color in the presence of growing dermatophytes.

Moreover, the medium is formulated to produce distinctive colony growth with typical identifying characteristics both macro and microscopically. The medium inhibits most Gram-positive and Gram-negative bacteria, yeast and saprophytic fungi. 

It is a single exposure system with dynamic built-in components and features that are designed for user compatibility and ease of detection.

Product Principle
  • Combine collection, culture, result and microscopic observation in one IVD device.  
  • Highly selective prepared media in a device designed for in-vitro specimen transport and incubation.
  • Rapid presumptive-positive diagnosis without re-plating. Intray can be placed directly on microscope stage
  • Fully enclosed cassette with Tyvek® air filtration prevents contamination and exposure, post-collection.   
Simple Convenience
  • InTray is designed for specimen collection/ inoculation at point-of-care
  • Saves time, material cost and waste, reducing exposure to collected sample
  • Place directly on the microscope tray for observation through the cassette’s clear anti-fog window
  • Selectively produces distinctive colony growth with typical identifiable morphology
