[citation needed] Substantially all coagulometers used in laboratory diagnostics are based on the methods of testing of the hemostasis system created more than fifty years ago.
Another problem of the actual hemostasis system diagnostics is the thrombosis prediction, i.e. sensitivity to the patient's prethrombotic state.
They suit to diagnose the general state of the blood coagulation system and the intensity of pathologies, and to simultaneously record all attendant influences.
Global methods play the key role at the first stage of diagnostics: they provide an integral picture of alterations within the coagulation system and allow predicting a tendency to hyper- or hypo-coagulation in general.
To obtain a complete picture of the work of hemostasis by a patient, the doctor should have a possibility to choose which test is necessary.
