  2. 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.

  3. Reference ranges for blood tests - Wikipedia

    en.wikipedia.org/wiki/Reference_ranges_for_blood...

    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 ...

  4. Immunoassay - Wikipedia

    en.wikipedia.org/wiki/Immunoassay

    In immunology the particular macromolecule bound by an antibody is referred to as an antigen and the area on an antigen to which the antibody binds is called an epitope. In some cases, an immunoassay may use an antigen to detect for the presence of antibodies, which recognize that antigen, in a solution.

  5. Latent autoimmune diabetes in adults - Wikipedia

    en.wikipedia.org/wiki/Latent_autoimmune_diabetes...

    A fasting blood sugar level of ≥ 7.0 mmol / L (126 mg/dL) is used in the general diagnosis of diabetes. [17] There are no clear guidelines for the diagnosis of LADA, but the criteria often used are that the patient should develop the disease in adulthood, not need insulin treatment for the first 6 months after diagnosis and have autoantibodies in the blood.

  6. Coombs test - Wikipedia

    en.wikipedia.org/wiki/Coombs_test

    The direct Coombs test detects antibodies that are stuck to the surface of the red blood cells. [1] Since these antibodies sometimes destroy red blood cells they can cause anemia; this test can help clarify the condition. The indirect Coombs test detects antibodies that are floating freely in the blood. [1]

  7. Hemagglutinin - Wikipedia

    en.wikipedia.org/wiki/Hemagglutinin

    This results in new subtype of hemagglutinins being created frequently, and is the cause of seasonal influenza outbreaks in humans. [ 14 ] Measles hemagglutinin : a hemagglutinin produced by the measles virus [ 15 ] that encodes six structural proteins , with hemagglutinin and fusion proteins being surface glycoproteins involved in attachment ...

  8. Hemagglutination assay - Wikipedia

    en.wikipedia.org/wiki/Hemagglutination_assay

    The most concentrated sample in the first well is often diluted to be 1/5x of the stock, and subsequent wells are typically two-fold dilutions (1/10, 1/20, 1/40, etc.).The final well serves as a negative control with no virus. Each row of the plate typically has a different virus and the same pattern of dilutions.

  9. Hemoglobin A2 - Wikipedia

    en.wikipedia.org/wiki/Hemoglobin_A2

    Normal levels range from 2.1-3.2%, but in the beta-thalassemia disorder, the levels increase to 3.5-6.0%. Additionally, individuals with beta-thalassemia exhibit a high red cell count and low hemoglobin levels. [3] Individuals that express lower levels of hemoglobin A2, have the a 0-thalassemia trait or homozygous gene for a +-thalassemia. [2]
