Low levels of platelets in turn may lead to prolonged or excessive bleeding. It is the most common coagulation disorder among intensive care patients and is seen in a fifth of medical patients and a third of surgical patients. [3] A normal human platelet count ranges from 150,000 to 450,000 platelets/microliter (μL) of blood. [4]
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.
If the platelet count is not known then assisted forms of delivery, for example forceps or ventouse, should be avoided to reduce the risk of harm. [19] If the delivery has been planned then antigen negative platelets should be available in case the infant's platelet count is low on a cord blood sample. [19]
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.
[1] [2] Kidney problems and low platelets then occur as the diarrhea progresses. [1] Children are more commonly affected, but most children recover without permanent damage to their health, although some children may have serious and sometimes life-threatening complications. [6] Adults, especially the elderly, may show a more complicated ...
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]
Idiopathic thrombocytopenic purpura (ITP) is the condition of having a low platelet count (thrombocytopenia) of no known cause . Recurrent thrombosis: Hemophilia: Hemophilia A: Hemophilia B: Hemophilia C: Von Willebrand disease: Antiphospholipid syndrome: Thrombocytopenia: Glanzmann's thrombasthenia: Wiskott–Aldrich syndrome
The platelet count may be slightly above the high limit of normal in iron-deficiency anemia (termed a mild thrombocytosis), but severe cases can present with thrombocytopenia (low platelet count). [58] Iron-deficiency anemia is confirmed by tests that include serum ferritin, serum iron level, serum transferrin, and total iron binding capacity. [59]
