As stated in the previous discussion of the pathogenesis of thrombosis, there are no general preoperative laboratory tests for platelets, coagulation, or fibrinolysis which can accurately predict whether or not a patient will develop a postoperative thrombus. In some cases a statistical difference has been demonstrated between two groups of patients — those developing thrombosis and those who do not — but in the individual case there is very little to go by. If it were possible to preoperatively identify patients who will develop postoperative thrombosis, selective prophylaxis would be possible. This would lower the costs of prophylaxis and also reduce the number of people being submitted to the risks involved.
