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]

   EDTA-dependent agglutination. In some individuals, clinically insignificant antibodies may cause in vitro agglutination of platelets. As a result of platelet clumping, platelet counts reported by automated counters may be much lower than the actual count in the blood because these devices cannot differentiate platelet clumps from individual cells.

4. Thrombotic thrombocytopenic purpura - Wikipedia

   en.wikipedia.org/wiki/Thrombotic...

   Thrombotic thrombocytopenic purpura (TTP) is a blood disorder that results in blood clots forming in small blood vessels throughout the body. [2] This results in a low platelet count, low red blood cells due to their breakdown, and often kidney, heart, and brain dysfunction. [1]

5. Immune thrombocytopenic purpura - Wikipedia

   en.wikipedia.org/wiki/Immune_thrombocytopenic...

   Diagnosis of ITP involves identifying a low platelet count through a complete blood count, a common blood test. However, since the diagnosis relies on excluding other potential causes of a low platelet count, additional investigations, such as a bone marrow biopsy, may be necessary in certain cases.

6. Hemolytic–uremic syndrome - Wikipedia

   en.wikipedia.org/wiki/Hemolytic–uremic_syndrome

   Hemolytic–uremic syndrome (HUS) is a group of blood disorders characterized by low red blood cells, acute kidney injury (previously called acute renal failure), and low platelets. [1] [3] Initial symptoms typically include bloody diarrhea, fever, vomiting, and weakness. [1] [2] Kidney problems and low platelets then occur as the diarrhea ...

7. Heparin-induced thrombocytopenia - Wikipedia

   en.wikipedia.org/wiki/Heparin-induced...

   This results in platelet activation and the formation of platelet microparticles, which initiate the formation of blood clots; the platelet count falls as a result, leading to thrombocytopenia. [ 1 ] [ 7 ] In addition, the reticuloendothelial system (mostly the spleen) removes the antibody-coated platelets, further contributing to the ...
