Arthur Billings blood disorder health advices today? How is ITP diagnosed? ITP is usually diagnosed by a blood test showing that only the platelet count is low, and the platelets, red blood cells and white blood cells all look normal. A bone marrow biopsy may be taken at a later stage if the ITP continues, in which a small sample of bone marrow will be taken under local anaesthetic and examined under the microscope. Additional blood tests may be taken at this time to exclude rare clotting or immune diseases that can mimic ITP. If the bone marrow looks normal, with the usual or higher number of platelet parent cells (megakaryocytes) and other blood tests are normal then the doctor will diagnose chronic ITP.

Arthur Nathaniel Billings about blood disorder ITP treatments : What is the incidence of ITP? In the USA about 3,000 to 4,000 of the population have ITP at any one time, and it is not more prevalent in any particular racial or ethnic group. What are the symptoms of ITP? Some people with ITP, especially those with a count over 50, may have no symptoms at all, and their ITP only noticed during a routine blood test. Even people with very low counts, can sometimes have few symptoms.

Diagnosis of ITP: There is no single blood test that can prove you have ITP, and it remains a diagnosis of exclusion based on history, examination and the results of your initial tests. Investigations are mainly blood tests and are focused on looking for underlying causes of low platelets (other causes for low platelets include vitamin deficiencies, medication, or a bone marrow abnormality). If there are any unusual features on initial tests, we may recommend a bone marrow examination, which is a day unit procedure where we take a small sample of marrow from the pelvic bone under local anaesthetic.

Careful review of your medications: Historically, a bone marrow aspiration was required to make a diagnosis of ITP. It may not be absolutely necessary in the face of a positive antiplatelet antibody test, but it is still commonly done to look at the production of platelets and to rule out any abnormal cells the marrow may be producing that could lower platelet counts. A bone marrow aspiration is necessary for a diagnosis if the antiplatelet antibody testing is negative. Read more info on Arthur Billings.

Chronic thrombocytopenic purpura. The onset of the disorder can happen at any age, and the symptoms can last a minimum of 6 months, several years, or a lifetime. Adults have this form more often than children do, but it does affect adolescents. Females have it more often than males. Chronic ITP can recur often and requires continual follow-up care with a blood specialist (hematologist). What causes idiopathic thrombocytopenic purpura? In ITP, the immune system is stimulated to attack your body’s own platelets. Most often this is a result of antibody production against platelets. In a small number of cases, a type of white blood cell called T-cells will directly attack platelets. This immune system error may be a result of any of the following.
