TraumaCheck Blood Disorder Identification Study

Study Purpose

You are being invited to participate in this study because you have one of the following bleeding disorders: platelet count deficiency, platelet dysfunction, low fibrinogen, FVII, FVIII or FIX deficiency or hyperfibrinolysis. The purpose of this research study is to test a new blood testing procedure. This blood testing procedure is using a device called TraumaCheck. It will be used to test blood in less than a minute for special cells in the blood that cause the blood to clot (clotting levels) with just a few drops of blood. It can take over an hour to get the same results from the laboratory. It can be done right at the bedside or in the doctor's office; hopefully in the future at home. Different factor products will be added to your blood in the laboratory to see the effect of the factor products on your blood levels.
