Elevated Plasma β-Thromboglobulin Levels in Multiple Myeloma and in Polycythaemia vera

Abstract
Plasma .beta.-thromboglobulin levels were determined in 22 multiple myeloma patients, in 15 patients with polycythemia vera and in 70 healthy controls. In multiple myeloma and polycythemia vera significantly increased plasma concentrations of this platelet-specific protein were found.
