TEST DETAILS
Interpretation guide:
Unit value
Result
Interpretation
< 36.0 u/mL Negative Absence of detectable VCA IgM antibodies. If exposure to Epstein-Barr virus is suspected despite a negative finding, a second sample should be collected and tested no less than one to two weeks later.
36.0 to 43.9 U/mL Equivocal Suggest a second sample be collected and tested one to two weeks later.
> 44.0 U/mL Positive Presence of detectable VCA IgM antibodies. Specific IgM antibodies are usually detected in patients with recent primary infection and may be found in patients with reactivated infections. Other EBV serology assays should be performed to confirm EBV-associated infectious mononucleosis.

Test includes:
Antibody detection to EBVCA IgM.
Methodology:
Chemiluminescence
Synonyms:
EB-IgM, EBV IGM
Epstein Barr IgM Antibody
Epstein Barr Virus IgM Antibodies to Viral Capsid
Clinical significance:
Epstein-Barr virus (EBV) is responsible for infectious mononucleosis (IM) and has also been implicated in Burkitt's lymphoma and nasopharyngeal carcinoma. EBV-VCA IgM antibodies typically appear within 4-6 weeks of infection with IM, peak concurrently with clinical onset of the disease, and decline within 2-3 months. A positive EBV-VCA IgM antibody in conjunction with clinical findings is indicative of an active or recent infection.
