Epstein-Barr Virus Antibody to Viral Capsid Antigen, IgM
Also known as: EBV M
Use
This test aids in the diagnosis of primary Epstein-Barr virus infectious mononucleosis when used in conjunction with other serologic tests. It is not a stand-alone test. Epstein-Barr virus (EBV) is a member of the Herpesvirus family and is associated with various diseases, including infectious mononucleosis, nasopharyngeal carcinoma, and certain lymphomas.
Special Instructions
Parallel testing is preferred, and convalescent specimens must be received within 30 days of receipt of the acute specimens. Label specimens clearly as 'acute' or 'convalescent.'
Limitations
EBV IgM values obtained with different assay methods may not be used interchangeably. The reported EBV IgM level's magnitude cannot be correlated to an endpoint titer. Contaminated, heat-inactivated, icteric, or grossly hemolyzed specimens are unacceptable.
