    It is an improvement on the Paul–Bunnell test. [2] The test is specific for heterophile antibodies produced by the human immune system in response to EBV infection. Commercially available test kits are 70–92% sensitive and 96–100% specific, with a lower sensitivity in the first two weeks after clinical symptoms begin. [3] [4]

    en.wikipedia.org/wiki/Epstein–Barr_virus...

    The Epstein–Barr virus nuclear antigen 2 (EBNA-2) is one of the six EBV viral nuclear proteins expressed in latently infected B lymphocytes is a transactivator protein. EBNA2 is involved in the regulation of latent viral transcription and contributes to the immortalization of EBV infected cells.

  4. Epstein–Barr virus–associated lymphoproliferative diseases (also abbreviated EBV-associated lymphoproliferative diseases or EBV+ LPD) are a group of disorders in which one or more types of lymphoid cells (a type of white blood cell), i.e. B cells, T cells, NK cells, and histiocytic-dendritic cells, are infected with the Epstein–Barr virus (EBV).

    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).

    Though EBNA1 is a well-characterized protein, its role in oncogenesis is less well defined. It is consistently expressed in EBV-associated tumors. [1] EBNA1 is the only identified latent protein-encoding genes that it consistently expressed in Burkitt's lymphoma cells [6] and is believed to contribute to EBV malignancies through B cell-directed expression.

    en.wikipedia.org/wiki/Enzyme_multiplied...

    Enzyme multiplied immunoassay technique (EMIT) is a common method for qualitative and quantitative determination of therapeutic and recreational drugs and certain proteins in serum and urine. [1] It is an immunoassay in which a drug or metabolite in the sample competes with a drug/metabolite labelled with an enzyme, to bind to an antibody. The ...
