Surface Testing Contact Plates from Health Care Logistics allow users to determine the efficacy of cleaning programs and hand washing techniques while also mitigating the risk for false negatives. Made using tryptic soy agar, the contact plates promote bacterial growth with neutralizing agents that prevent growth interference from cleaners and disinfectants. Testing can be done in labs, cleanrooms, and other areas where surface contaminants and sterility are concerns, and reliable results contribute to increased patient safety. When performed and documented regularly, environmental control can be demonstrated and monitored; further, Health Care Logistics can help create site-specific environmental monitoring plans that include contact plate testing. This process can provide valuable information and identify issues before they impact sterility, integrity, and patient safety.
