Glandular Fever Screen

Limitations for infectious mononucleosis (glandular fever): the test detects heterophile antibodies in whole blood. Approximately 10% of adults and up to 40% of children under the age of 5 years do not produce these antibodies so will give a negative screening test. Always consider the test result in combination with clinical symptoms and results of the white cell differential.
