Abstract
Several discrepancies in the description of the coagulation data presented in the article by Schiller and others1 are apparent. A patient with "definite" Factor X deficiency of a clinically severe degree should have an abnormal prothrombin time and thromboplastin generation test. The authors report these tests to be within normal limits. Also, a platelet adhesiveness of 74% is hardly "slightly reduced" by most published normal values which range from 20 to 80%. In addition, if "A.P.T.T." means "a partial thromboplastin time," then this test should also be abnormal.
