    The most popular test detects VZV-specific IgM antibody in blood; this appears only during chickenpox or shingles and not while the virus is dormant. [52] In larger laboratories, lymph collected from a blister is tested by polymerase chain reaction (PCR) for VZV DNA, or examined with an electron microscope for virus particles. [ 53 ]

    To do this, antibodies that are specific to different types of viruses are mixed with the tissue sample. After the tissue is exposed to a specific wavelength of light or a chemical that allows the antibody to be visualized. [citation needed] These tests require specialized antibodies that are produced and purchased from commercial companies.

  4. Serology - Wikipedia

    en.wikipedia.org/wiki/Serology

    Serology is the scientific study of serum and other body fluids.In practice, the term usually refers to the diagnostic identification of antibodies in the serum. [1] Such antibodies are typically formed in response to an infection (against a given microorganism), [2] against other foreign proteins (in response, for example, to a mismatched blood transfusion), or to one's own proteins (in ...

  5. Seroconversion - Wikipedia

    en.wikipedia.org/wiki/Seroconversion

    Serological assays are tests that detect specific antibodies and are used to determine whether those antibodies are in an organism's blood; such tests require a significant concentration of unbound antibody in the blood serum. Serostatus is a term denoting the presence or absence of particular antibodies in an individual's blood. An individual ...

  6. Blood compatibility testing - Wikipedia

    en.wikipedia.org/wiki/Blood_compatibility_testing

    Blood compatibility testing is routinely performed before a blood transfusion.The full compatibility testing process involves ABO and RhD (Rh factor) typing; screening for antibodies against other blood group systems; and crossmatching, which involves testing the recipient's blood plasma against the donor's red blood cells as a final check for incompatibility.

  7. Blood test - Wikipedia

    en.wikipedia.org/wiki/Blood_test

    Multiple tests for specific blood components, such as a glucose test or a cholesterol test, are often grouped together into one test panel called a blood panel or blood work. Blood tests are often used in health care to determine physiological and biochemical states, such as disease , mineral content, pharmaceutical drug effectiveness, and ...

  8. 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.

  9. Antibody elution - Wikipedia

    en.wikipedia.org/wiki/Antibody_elution

    An antibody elution removes bound antibody from the surface of a red blood cell to aid in the antibody identification process. An antibody elution is a clinical laboratory diagnostic procedure which removes sensitized antibodies from red blood cells , in order to determine the blood group system antigen the antibody targets.
