Thrombocythemia Thrombocythemia: Introduction. Thrombocythemia: A haematological disorder in which there is excessive proliferation of platelet precursor cells, resulting in increased numbers of platelets in the blood. More detailed information about the symptoms, causes, and treatments of Thrombocythemia is available below.

Immune Thrombocytopenia  (ITP) Immune thrombocytopenia (THROM-bo-si-toe-PE-ne-ah), or ITP, is a bleeding disorder. In ITP, the blood doesn't clot as it should. This is due to a low number of blood cell fragments called platelets (PLATE-lets) or thrombocytes (THROM-bo-sites). Platelets are made in your bone marrow along with other kinds of blood cells.

Thrombocytopenia (Low Platelet Count) What is thrombocytopenia (low platelet count)? Platelets (thrombocytes) are important elements in the blood that are important for blood coagulation (clotting and prevention of bleeding). Thrombocytopenia refers to having low platelet count in the blood compared to the normal range. The normal platelet count ranges between 150,000 and 450,000 per microliter (one-millionth of a liter).

thrombocytosis Thrombocytosis is an abnormally increased number of platelets in the blood. Platelets are blood cells that stick together, helping blood to clot. Thrombocytosis is a condition that may have many causes. Throbocytosis is classified as one of two types. Secondary thrombocytosis can be traced to another cause, such as inflammation, severe bleeding, iron deficiency, or some cancers.

Primary Thrombocythemia Back to Top Causes. Primary thrombocythemia is caused by too much growth of a type of cell that is used to make blood cells. The platelets are mostly affected, but the red blood cells and white blood cells may be involved as well. This condition slowly gets worse over time.

Thrombocythemia From Wikipedia, the free encyclopedia. Thrombocytosis (or thrombocythemia) is the presence of high platelet counts in the blood, and can be either primary (also termed essential and caused by a myeloproliferative disease) or reactive (also termed secondary).hrombocytosis can be contrasted with thrombocytopenia, a loss of platelets in the blood. In a healthy individual, a normal platelet count ranges from 150,000 and 450,000 per mm³ (or microlitre) (150–450 x 10 9 / L).

Thrombocytosis Thrombocytosis is defined as a platelet count above the upper limit of the normal range (450 x 10 9 /L in adults). This article aims to outline diagnosis, investigation and management of patients with thrombocytosis and to highlight possible complications.

Thrombotic thrombocytopenic purpura thrombotic thrombocytopenic purpura. Description. Thrombotic thrombocytopenic purpura is a rare disorder that causes blood clots (thrombi) to form in small blood vessels throughout the body. These clots can cause serious medical problems if they block vessels and restrict blood flow to organs such as the brain, kidneys, and heart.

- Heparin-induced thrombocytopenia (HIT) is a life-threatening complication of exposure to heparin (ie, unfractionated heparin, low molecular weight [LMW] heparin) that occurs in up to 5 percent of patients exposed, regardless of the dose, schedule, or route of administration.

Thrombocytopenia (Low Platelet Counts) Thrombocytopenia refers to the presence of abnormally low levels of platelets in the circulating blood. Platelets, or thrombocytes, are a specific kind of blood cell that prevent bleeding. The most common reason that cancer patients experience thrombocytopenia is as a side effect of chemotherapy. When chemotherapy affects bone marrow, the body’s ability to produce platelets, the body’s chief defense against bleeding, is diminished. Platelets normally rush to the site of an injury and work with other blood factors to from a blood clot.

Gestational thrombocytopenia Gestational thrombocytopenia. Gestational (incidental) thrombocytopenia is a condition that commonly affects pregnant women. Thrombocytopenia is defined as the drop in platelet count from the normal range of 150,000 –400,000 / μL to a count lower than 150,000 / μL.

Thrombocytosis In essential thrombocythemia, there is a much higher risk of clotting or bleeding complications. Therefore, if your blood test results reveal a high platelet count, it's important for your doctor to determine whether you have essential thrombocythemia or reactive thrombocytosis. Reactive thrombocytosis causes include: 1  Acute bleeding and blood loss. 2  Allergic reactions. 3  Cancer.

Thrombocytopenia Thrombocytopenia means you don't have enough platelets, cells in your blood that stick together to help it clot. It might not cause you any health problems at all. But if you do have symptoms like bleeding too much, treatments can help. Platelets are made in your bone marrow, the spongy tissue inside your bones.

Thrombocytosis This condition often is called secondary or reactive thrombocytosis. Secondary thrombocytosis is more common than primary thrombocythemia. Often, a high platelet count doesn't cause signs or symptoms. Rarely, serious or life-threatening symptoms can develop, such as blood clots and bleeding. These symptoms are more likely to occur in people who have primary thrombocythemia.

Thrombocytosis Thrombocytosis is typically discovered as an incidental laboratory abnormality when the complete blood count is obtained for some unrelated reason. When found, however, it creates an important diagnostic challenge. Thrombocytosis generally either is a reactive process (secondary thrombocytosis) or is caused by a clonal bone marrow (myeloproliferative) disorder; the latter category includes essential thrombocythemia.

Polycythemia Polycythemia (also known as polycythaemia or polyglobulia) is a disease state in which the proportion of blood volume that is occupied by red blood cells increases.Blood volume proportions can be measured as hematocrit.he emergency treatment of polycythemia (e.g., in hyperviscosity or thrombosis) is by venesection, the removal of blood from the circulation. Depending on the underlying cause, venesection may also be used on a regular basis to reduce the red blood cell count.

Thrombocytopenia (Low Platelet Count) 1 Thrombocytopenia refers to an abnormally low level of platelets in the bloodstream. 2  Platelets are important for normal blood clotting. 3  With severe thrombocytopenia, excessive bleeding may occur.  Thrombocytopenia occurs because there is decreased production or increased destruction of platelets.
