Platelet consumption and plasma concentration of platelet factor 4 (PF-J)

In 10 cancer patients platelet concentration, platelet consumption, platelet half-life time and plasms concentrations of platelet factor 4 were determined. A high freguency of thrombocytosis and increased platelet consumption were observed, and the plasms concentrations of platelet factor 4 was increased. However, no significant correlation was found between platelet consumption and the result of a single determination of platelet factor 4 concentrations in plasma.
