Testing your washer-disinfector(s) daily is considered best practice and is vital to ensuring optimum surgical instrument cleaning performance. To test the function of your washer-disinfector, use T-EZ Pro™ to verify the effective removal of surgical soil from instruments and medical devices during the mechanical cleaning process. T-EZ Pro uses a standardized true blood test soil as a verification indicator, an accurate representation of the most common contamination found in healthcare.
