The Thrombogram describes the concentration of thrombin in clotting plasma and is therefore a general physiologic function test of the thrombotic hemostatic system. The CAT measures thrombotic as well as bleeding tendency and can be used
The method uses the Thrombinoscope™ software available from Thrombinoscope BV and is intended for research purposes only. Our patented technique is measured on a Thrombinograph™, a 96-well plate fluorimeter available from Thermo Scientific, and uses a thrombin calibrator that is needed to correct for inner filter effect, donor-to-donor variability in color of plasma, substrate depletion and instrumental differences.
Thrombin is often seen as the end-product of the coagulation cascade and as such responsible for the final step, the conversion of the soluble protein fibrinogen into the insoluble fibrin clot. However, the coagulation cascade has so many (nested) feedback loops and inhibitory pathways that are all directly or indirectly influenced by the developing thrombin concentration that thrombin plays a central and pivotal role throughout the whole process. This makes the description of the concentration of thrombin in time an excellent tool to obtain a full picture of coagulability.
