003652. [edit on Wikidata] Clotting time is a general term for the time required for a sample of blood to form a clot, or, in medical terms, coagulate. The term "clotting time" is often used when referring to tests such as the prothrombin time (PT), activated partial thromboplastin time (aPTT or PTT), activated clotting time (ACT), thrombin ...
003656. [edit on Wikidata] Bleeding time is a medical test done on someone to assess their platelets function. It involves making a patient bleed, then timing how long it takes for them to stop bleeding using a stopwatch or other suitable devices. The term template bleeding time is used when the test is performed to standardized parameters.
Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...
A temperature between 101–102 is considered a mild fever, 102–103 a moderate, and 104 or above a high fever, and delirium or convulsions may occur. From birth until adolescence, temperature between 99.8–100.8 is considered a low-grade fever. If the temperature is taken rectally, it is not considered a fever until it is above 100.4.
0.6-2.5/100,000 cases per year. [ 2 ] In hematology, essential thrombocythemia (ET) is a rare chronic blood cancer (myeloproliferative neoplasm) characterised by the overproduction of platelets (thrombocytes) by megakaryocytes in the bone marrow. [ 3 ] It may, albeit rarely, develop into acute myeloid leukemia or myelofibrosis. [ 3 ]
In a typical set of rules, a platelet donor must weigh at least 50 kg (110 lb) and have a platelet count of at least 150 x 10 9 /L (150,000 platelets per mm³). [2] One unit has greater than 3×10 11 platelets. Therefore, it takes 2 liters of blood having a platelet count of 150,000/mm³ to produce one unit of platelets.
The normal range for a healthy person not using warfarin is 0.8–1.2, and for people on warfarin therapy an INR of 2.0–3.0 is usually targeted, although the target INR may be higher in particular situations, such as for those with a mechanical heart valve. If the INR is outside the target range, a high INR indicates a higher risk of bleeding ...
Platelet concentrations vary between individuals and over time, with the population average between 250,000 and 260,000 cells per mm 3 (equivalent to per microliter), but the typical laboratory accepted normal range is between 150,000 and 400,000 cells per mm 3 or 150–400 × 10 9 per liter.
