Hardy Diagnostics' Catalase Reagents are useful in the presumptive identification and differentiation of many bacteria. Beta-hemolytic organisms, such as Streptococcus species (catalase-negative), Staphylococcus species (catalase-positive), and Listeria species (catalase-positive) can be differentiated by their catalase reaction using 3% hydrogen peroxide. For catalase testing of anaerobic bacteria, 15% hydrogen peroxide appears to be more sensitive than 3% hydrogen peroxide. The Hardy Diagnostics manufacturing facility and quality management system comply with the FDA's Good Manufacturing Practices (GMP) and have achieved ISO 13485 certification as a medical device manufacturer
