Infectious Mononucleosis (also known as Glandular Fever) is a widespread viral disease caused by the Epstein-Barr Virus (EBV), it is primarliy a disease of adolescents and young adults as >90% adults have acquired immunity by the age of 40. When exposed as children most people only develop flu-like symptoms. In the adolescents and young adults the disease is characterised by fever, sore throat, fatigue and swollen lymph nodes. The screening test uses a card system in which a drop of blood

Read MoreInfectious Mononucleosis Slide Test (Clearview IM II)
Limitations of Test Procedure
The Clearview IM II detects IM heterophile antibodies associated with EBV infection. These are present in 80-90% of acute IM infections and can be detected in 60-70% of patients during the first week of clinical illness.
Negative results can be obtained when insufficient levels of antibody are present. Where clinically indicated, or other laboratory results suggest, a repeat test should be performed on negative samples. A NEGATIVE result does not at any time preclude the possibility of IM infection.
If the test is negative and clinical symptoms persist, additional testing using other clinical methods is recommended.
The Clearview IM II is a qualitative in vitro diagnostic test. Neither the quantitative value nor the rate of increase in the IM antibody concentration can be determined by this qualitative test.
Heterophile antibodies can also be demonstrated in rheumatoid arthritis, viral hepatitis, leukaemia and Burkett’s lymphoma.
