  2. Coombs test - Wikipedia

    en.wikipedia.org/wiki/Coombs_test

    The direct Coombs test is used to detect antibodies or complement proteins attached to the surface of red blood cells. To perform the test, a blood sample is taken and the red blood cells are washed (removing the patient's plasma and unbound antibodies from the red blood cells) and then incubated with anti-human globulin ("Coombs reagent").

  3. Immunoglobulin E - Wikipedia

    en.wikipedia.org/wiki/Immunoglobulin_E

    Diagnosis of allergy is most often done by reviewing a person's medical history and finding a positive result for the presence of allergen specific IgE when conducting a skin or blood test. [33] Specific IgE testing is the proven test for allergy detection; evidence does not show that indiscriminate IgE testing or testing for immunoglobulin G ...

  4. 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 ...

  5. Radioallergosorbent test - Wikipedia

    en.wikipedia.org/wiki/Radioallergosorbent_test

    The RAST is a radioimmunoassay test to detect specific IgE antibodies to suspected or known allergens for the purpose of guiding a diagnosis about allergy. [10] [11] IgE is the antibody associated with Type I allergic response: for example, if a person exhibits a high level of IgE directed against pollen, the test may indicate the person is allergic to pollen (or pollen-like) proteins.

  6. Immunofixation - Wikipedia

    en.wikipedia.org/wiki/Immunofixation

    The panel simultaneously tests 4 patients (one in each quadrant). Each patient has 6 electrophoresis panels: The left one is a conventional serum protein electrophoresis . The remainder get solutions with anti-IgG, anti-IgA, anti-IgM, anti-kappa light chain and anti-lambda light chain immunoglobulin, respectively from left to right.

  7. Serum protein electrophoresis - Wikipedia

    en.wikipedia.org/wiki/Serum_protein_electrophoresis

    Fibrinogen from plasma samples will be seen in the beta gamma region. Fibrinogen, a beta-2 protein, is found in normal plasma but absent in normal serum. Occasionally, blood drawn from heparinized patients does not fully clot, resulting in a visible fibrinogen band between the beta and gamma globulins. [citation needed]

  8. Gamma globulin - Wikipedia

    en.wikipedia.org/wiki/Gamma_globulin

    Gamma globulin injections are usually given in an attempt to temporarily boost a patient's immunity against disease. Injections are most commonly used on patients having been exposed to hepatitis A or measles , or to make a kidney donor and a recipient compatible regardless of blood type or tissue match.

  9. Immunoassay - Wikipedia

    en.wikipedia.org/wiki/Immunoassay

    An immunoassay (IA) is a biochemical test that measures the presence or concentration of a macromolecule or a small molecule in a solution through the use of an antibody (usually) or an antigen (sometimes).
