Chromogenic Media for UTI Isolation

Rapid Chromogenic Urine Isolation Media

HardyCHROM UTI is a non-selective chromogenic medium recommended for the cultivation, differentiation and enumuration of urinary tract pathogens based on colony colour and morphology with only a minimum of confirmatory tests.
