Rarely, however, a false positive heterophile antibody test may result from systemic lupus erythematosus, toxoplasmosis, rubella, lymphoma and leukemia. [7] However, the sensitivity is only moderate, so a negative test does not exclude EBV. This lack of sensitivity is especially the case in young children, many of whom will not produce ...
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.
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).
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.
The Epstein–Barr virus nuclear antigen 3 (EBNA-3) is a family of viral proteins associated with the Epstein–Barr virus. A typical EBV genome contains three such proteins: [1] EBNA-3A (, EBNA-3; BLRF3-BERF1) EBNA-3B (, EBNA-4; BERF2A-BERF2B) EBNA-3C (, EBNA-6, EBNA-4B; BERF3-BERF4) These genes also bind the host RBP-Jκ protein.

Autoantibodies are usually absent or very low, so instead of being given in standard reference ranges, the values usually denote where they are said to be present, or whether the test is a positive test. There may also be an equivocal interval, where it is uncertain whether there is a significantly increased level.
