HardyCHROM™ Group A Strep

Hardy Diagnostics is proud to introduce
HardyCHROM™ Group A Strep Agar

Straight Forward. Easy-to-read. Color Differentiation.

We are making identification easy with the release of the Hardy Diagnostics HardyCHROM™ Group A Strep Agar.

Our new chromogenic medium allows for an easy-to-read and straight forward selective cultivation and differential isolation of Group A Streptococcus (S. pyogenes) or GAS.

GAS can be differentiated on this medium based on colony color (red, red-brown, or red-orange colonies) among other non-GAS bacteria that are part of the throat flora (blue, clear, or white colonies) after 24 hours of incubation.

Catalog no. G337
