Clinical Info
The test is used as an aid in diagnosing recent EBV infection. It should ne done in conjunction with EBV VCA IgG and EBV nuclear antigen IgG tests. Clinical correlation is required.
Clinical Limitation
Assay performance has not been established for immunocompromised or immunosuppressed patients. Assay performance has not been established for cord blood, neonatal specimens or infants. Due to a degree of observed cross-reactivity in some CMV and Toxo IgM positive samples, samples positive for these analytes should be interpreted with caution. Assay performance has not been established for the diagnosis of nasopharyngeal carcinoma, Burkitt's lymphoma, other EBV-associated lymphomas, and other EBV associated diseases other than EBV related mononucleosis. Testing should not be performed as a screening procedure for the general population. It should only be performed when clinical evidence suggests the diagnosis of EBV-associated infectious mononucleosis. In cases of equivocal results, a second freshly collected sample should be obtained and tested.
