The mononucleosis spot test looks for two antibodies in the blood that indicate infection with the Epstein-Barr virus (EBV).
. It is used to diagnosis infectious mononucleosis, a disease caused by the Epstein-Barr virus (EBV). About 1 week after the onset of the disease, many patients develop heterophile antibodies. Antibodies reach peak levels in 2 - 5 weeks and may persist for up to 1 year. However, a small number of persons with mononucleosis may never develop such antibodies.
Monospot tests are usually positive in approximately 85% of patients with infectious mononucleosis. Positive test results will not occur until 1 - 2 weeks into the illness.
