  2. 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.

  3. Fluorescence polarization immunoassay - Wikipedia

    en.wikipedia.org/wiki/Fluorescence_polarization...

    The tracer and the specific antigen will compete to bind to the antibody and if the antigen is low in concentration, more tracer will be bound to the antibody resulting in a higher fluorescence polarization and vice versa. [7] A conventional FPIA follows the procedure below: A specific quantity of sample is added to reaction buffer.

  4. Viral disease testing - Wikipedia

    en.wikipedia.org/wiki/Viral_disease_testing

    Antigen tests can be analyzed within a few minutes. Antigen tests are less accurate than PCR tests. It has a low false positive rate, but a higher false negative rate. A negative test result may require confirmation with a PCR test. [8] Advocates claim that antigen tests are less expensive and can be scaled up more rapidly than PCR tests. [8]

  5. COVID-19 testing - Wikipedia

    en.wikipedia.org/wiki/COVID-19_testing

    COVID-19 rapid antigen tests are lateral flow immunoassays that detect the presence of a specific viral antigen, which indicates current viral infection. Antigen tests produce results quickly (within approximately 15–30 minutes), and most can be used at the point-of-care or as self-tests.

  6. Immunolabeling - Wikipedia

    en.wikipedia.org/wiki/Immunolabeling

    This indirect method employs a primary antibody that is antigen-specific and a secondary antibody fused to a tag that specifically binds the primary antibody. This indirect approach permits mass production of secondary antibody that can be bought off the shelf. [4] Pursuant to this indirect method, the primary antibody is added to the test system.

  7. Magnetic immunoassay - Wikipedia

    en.wikipedia.org/wiki/Magnetic_immunoassay

    MIA involves the specific binding of an antibody to its antigen, where a magnetic label is conjugated to one element of the pair. The presence of magnetic beads is then detected by a magnetic reader (magnetometer) which measures the magnetic field change induced by the beads. The signal measured by the magnetometer is proportional to the ...

  8. Blood compatibility testing - Wikipedia

    en.wikipedia.org/wiki/Blood_compatibility_testing

    When multiple antibodies are present, or when an antibody is directed against a high-frequency antigen, the normal antibody panel procedure may not provide a conclusive identification. In these cases, hemagglutination inhibition can be used, wherein a neutralizing substance cancels out a specific antigen. [17]

  9. Immunocytochemistry - Wikipedia

    en.wikipedia.org/wiki/Immunocytochemistry

    Immunocytochemistry is a technique used to assess the presence of a specific protein or antigen in cells (cultured cells, cell suspensions) by use of a specific antibody, which binds to it, thereby allowing visualization and examination under a microscope. It is a valuable tool for the determination of cellular contents from individual cells.
