Hart Biologicals offers a range of products used in the diagnosis and treatment of many disorders of the haemostatic system. In San Diego we will advertise our company and display its reagents with a special focus on the soon to be marketed Fiix-prothrombin time (Fiix-test). The Fiix-test is a new prothrombin time test that is sensitive only to reduced factors II and X. The Fiix-PT was shown in an RCT to lead to more stable warfarin anticoagulation by removing the influence of factor VII.
