Characteristic Electrophoretic Patterns in Hemophilia and Idiopathic Thrombocytopenia.

Summary Characteristic electrophoretic patterns have been observed in all 5 cases of hemophilia and in all 8 cases of idiopathic thrombocytopenic purpura. These patterns show the following characteristics: (a) appearance of an unusual peak in the group of the α-globulins (αx), and (b) disappearance of the usual α2- and α3-globulin peaks. The same anomaly has been observed in some cases of secondary thrombocytopenia, “anaphylactoid” type of vascular purpura, and hemolytic anemia with evidence of platelet dysfunction.
