Vacuolization may be present in a cell that has recently phagocytized foreign matter. A monocyte count is part of a complete blood count and is expressed either as a ratio of monocytes to the total number of white blood cells counted, or by absolute numbers. Both may be useful in determining or refuting a possible diagnosis. Monocytosis is the state of excess monocytes in the peripheral blood.
The mononucleosis test is used to help determine whether a person with symptoms has infectious mononucleosis (mono). The test is used to detect proteins in the blood called heterophile antibodies that are produced by the immune system in response to an Epstein-Barr virus (EBV) infection, the most common cause of mono. A mono test is frequently ordered along with a complete blood count (CBC). The CBC is used to determine whether the number of white blood cells (WBCs) is elevated and whether a significant number of reactive lymphocytes are present. Mono is characterized by the presence of atypical white blood cells.
