2. Thrombocytopenia - Wikipedia

   en.wikipedia.org/wiki/Thrombocytopenia

   One common definition of thrombocytopenia requiring emergency treatment is a platelet count below 50,000/μL. [5] Thrombocytopenia can be contrasted with the conditions associated with an abnormally high level of platelets in the blood – thrombocythemia (when the cause is unknown), and thrombocytosis (when the cause is known). [6] [7]

3. Thrombocythemia - Wikipedia

   en.wikipedia.org/wiki/Thrombocythemia

   Reactive thrombocythemia is the most common cause of a high platelet count. It accounts for 88% to 97% of thrombocythemia cases in adults, and near 100% in children. In adults, acute infection, tissue damage, chronic inflammation and malignancy are the common causes of reactive thrombocythemia. Usually, one or more of these conditions is ...

4. Giant platelet disorder - Wikipedia

   en.wikipedia.org/wiki/Giant_platelet_disorder

   Giant platelet disorder; Two giant platelets (stained purple) are visible in this image from a light microscope (40×) from a peripheral blood smear surrounded by red blood cells. One normal platelet can be seen in the upper left side of the image (purple) and is significantly smaller in size than the red blood cells (stained pink). Specialty ...

   Class 3: Volume loss from 30% to 40% of total blood volume, from 1500 mL to 2000 mL. A significant drop in blood pressure and changes in mental status occur. [3] Heart rate and respiratory rate are significantly elevated (more than 120 BPM). Urine output declines. Capillary refill is delayed. [3] Class 4: Volume loss over 40% of total blood volume.

6. Plateletpheresis - Wikipedia

   en.wikipedia.org/wiki/Plateletpheresis

   Some regular donors have higher platelet counts (over 300,000/mm³); for those donors, it only takes about one liter of their blood to produce a unit. Since the machine used to perform the procedure uses suction to draw blood out of a donor's body, some people who can give whole blood may have veins too small for platelet donation.

7. Essential thrombocythemia - Wikipedia

   en.wikipedia.org/wiki/Essential_thrombocythemia

   Hydroxycarbamide, interferon-α and anagrelide can lower the platelet count. Low-dose aspirin is used to reduce the risk of blood clot formation unless the platelet count is very high, where there is a risk of bleeding from the disease, and hence this measure would be counter-productive as aspirin-use increases the risk of bleeding. [3] [15 ...
