Platelet Satellitism in a Three and Half Year Old Girl with Hemolytic Anemia and Normal Platelet Count
Platelet adherence surrounding leucocytes in a rosette formation or platelet satellitism is a rare phenomenon. This finding has been observed almost exclusively in Ethylenediaminetetraacetic acid treated blood at room temperature. The mechanism underlying this phenomenon is not fully understood. In many reports of platelet satellitism platelets clump to polymorphonuclear neutrophils in healthy...
متن کاملInternational Normalized Ratio ( Inr )
Prothrombin time can be measured roughly on whole blood as in neonates, but is more commonly measured from plasma. Blood is taken into a vacutainer containing liquid citrate. Citrate acts as an anticoagulant by consuming all the calcium in the sample. The blood is mixed and centrifuged to separate blood cells from the plasma. The plasma is placed in a coagulation machine which takes a sample of...

Dear Madam, The P.T. assay, first described in 1935 by Quick et al. soon became the monitoring of oral anticoagulant therapy. The P.T. measures the affect of reduction in the Vit. K dependent coagulant factors II, VII and X. Because the Prothrombin Time Ratio (P.T.R.) is markedly affected by the activity of thromboplastin, the W. It helps to determine the intensity of anti-coagulation therapy b...
متن کاملMean platelet volume/platelet count ratio is associated with prognosis in patients with pancreatic cancer
An increased mean platelet volume (MPV) is recognized as an early marker of platelet activation. The diagnostic and prognostic impact of the MPV and MPV/platelet count (PC) ratio in some cancers has recently been reported. The aim of this study was to evaluate the prognostic significance of preoperative MPV/PC ratio in pancreatic cancer. A total of 124 pancreatic cancer patients were included i...
متن کاملProblems with the international normalized ratio.
In a recent letter to Blood, Hirsh called attention to the inadequacy of monitoring warfarin dosage by the prothrombin time assay (PT) as commonly performed in the United States.’ The actual PT value may vary widely from laboratory to laboratory because the result is dependent on the “responsiveness” of the thromboplastin used for the test, and because the thromboplastin reagents distributed co...
