Résumé :

The calibrated and automated thrombinography (CAT) developed by H.C. Hemker is a simple and reproducible technique that can be potentially used in coagulation laboratories. This test is able to record the complete thrombin generation in vitro, giving an interesting approach in the evaluation of the haemostatic potential at the individual level. We aimed to implement this test in our laboratory to follow patients with haemorrhagic or thrombotic pathologies. Haemorrhagic and thrombotic disorders are incompletely explored by the coagulation tests used presently in routine labs. These tests don't indeed reflect the real haemostatic phenotype of the patient neither the individual response to haemostatic treatments. Furthermore, they don't have any predictive value for the occurrence of haemorrhage and/or thrombosis. We report here reference values we established in a population of children and adults in pre-analytical conditions easily applicable in coagulation labs. Platelet poor plasma is prepared by a double centrifugation and analyzed immediately or frozen at -80 degrees C for delayed analysis.
