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. Pseudothrombocytopenia - Wikipedia

   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. Gestational thrombocytopenia - Wikipedia

   en.wikipedia.org/wiki/Gestational_thrombocytopenia

   Generally, there is a decrease in platelet count in pregnant women and it will be due to many reasons. [1] The two main causes of thrombocytopenia are a decrease in the production of platelets in the bone marrow and an increase in the destruction of the platelets. [4]

6. 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 ...

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 thrombocytopenia.
