 Hemocompatibility testing is an essential step in evaluating the safety of medical devices before they can be used in humans. This process involves assessing the potential risk of blood contacting materials by studying how they interact with blood components such as red blood cells, white blood cells, platelets, and clotting factors. Testing methods include agitated and sheer flow models which measure hemolysis, cell counts, and activation of the coagulation and complement systems. Additionally, the surface of the device is evaluated for its ability to attach blood cells, protein absorption, and the formation of thrombi and fibrin networks. These tests provide valuable information about the potential risks associated with using these materials in patients.
