Infectious mononucleosis (IM) is an acute, self-limited, lymphoproliferative disease caused by the Epstein-Barr virus (EBV). Infection with EBV usually occurs early in life with no recognizable disease. When primary infection is delayed until young adulthood and adolescence, there is about a 50% chance that it will occur with the classic clinical manifestations associated with IM. The diagnosis of IM is usually based on the evaluation of characteristic clinical, hematological, and serological changes. In most cases of IM, clinical diagnosis can be made from the characteristic triad of fever, pharyngitis, and cervical lymphadenopathy, lasting for 1 to 4 weeks.
IM may be complicated by splenomegaly, hepatitis, pericarditis, or central nervous system involvement. Rare fatal primary infections occur in patients with histiocytic hemophagocytic syndrome or with a genetic X-linked lymphoproliferative syndrome. Hematologic features of IM include lymphocytosis with prominent atypical lymphocytes. Because other diseases may mimic the clinical and hematological symptoms of IM, serological testing is essential for the most accurate diagnosis. Serological diagnosis of IM is demonstrated by the presence of heterophile and EBV antibodies in the sera of patients.
It has been well established that most individuals exposed to EBV develop a heterophile antibody response. Heterophile antibodies make up a broad class of antibodies which are characterized by the ability to react with surface antigens present on erythrocytes of different mammalian species. It is not known which specic antigen stimulates their production. It has been a common practice for physicians to use the detection of IM heterophile antibodies in the blood of patients as an aid in the diagnosis of IM.
Accutest® Rapid Mono assay utilizes an extract of bovine erythrocytes which gives a greater sensitivity and specicity than similar extracts prepared from sheep and horse erythrocytes.
The Forssman antibody interference has been known to be minimized by using the bovine erythrocyte extract.
