In a typical set of rules, a platelet donor must weigh at least 50 kg (110 lb) and have a platelet count of at least 150 x 10 9 /L (150,000 platelets per mm³). [2] One unit has greater than 3×10 11 platelets. Therefore, it takes 2 liters of blood having a platelet count of 150,000/mm³ to produce one unit of platelets.
The use of cytochalasin is more favorable than using glycoprotein IIb/ IIIa inhibitors which block platelet incompletely, especially at higher platelet counts. [18] FIBTEM allows for the detection of fibrinogen deficiency or fibrin polymerization disorders, e.g. induced by certain plasma expanders, and may identify rapidly the need to ...
Platelet count (Plt) A few values are for inside red blood cells only: ... Immature platelet fraction (IPF) Adult: 0.8 [141] 5.6 [141] % White blood cells.
In hematology, thrombocythemia is a condition of high platelet (thrombocyte) count in the blood. Normal count is in the range of 150 × 10 9 to 450 × 10 9 platelets per liter of blood, [ 1 ] but investigation is typically only considered if the upper limit exceeds 750 × 10 9 /L.
platelet count; bleeding time for platelet function; PR (prothrombin ratio) for the tissue factor pathway (extrinsic pathway) aPTT (Activated Partial Thromboplastin time) for the contact activation pathway (intrinsic pathway) TCT or fibrinogen assay for final common pathway (THROMBIN TIME) Two other tests are regularly performed at the same time:
leukopenia: total white cell count < 4.0 x 10 9 /L. Decrease in all types of white blood cells (revealed by doing a differential count). thrombocytopenia : platelet count < 150×10 9 /L. Treatment
A white blood cell differential is a medical laboratory test that provides information about the types and amounts of white blood cells in a person's blood. The test, which is usually ordered as part of a complete blood count (CBC), measures the amounts of the five normal white blood cell types – neutrophils, lymphocytes, monocytes, eosinophils and basophils – as well as abnormal cell ...
Mean platelet volume (MPV) is a machine-calculated measurement of the average size of platelets found in blood and is typically included in blood tests as part of the CBC. Since the average platelet size is larger when the body is producing increased numbers of platelets, the MPV test results can be used to make inferences about platelet ...
