Presence of VCA IgM antibodies indicates recent primary infection with Epstein-Barr virus (EBV). I have since dedicated my clinical work to EBV – and sure enough, the more they test for EBV, the more EBV we find. Serology remains the mainstay for diagnosis of Epstein–Barr virus (EBV) infection. EBV stands for Epstein-Barr virus. Epstein-Barr Virus Antibody to Nuclear Antigen, IgG. The EBV Panel looks for four types of antibodies to provide a comprehensive screening for Epstein-Barr Virus. If it is negative, this means you are susceptible to the virus. VCA-IgM denotes current or reactivated infection. Because IgG antibodies to HSV persist for life, serologic assays can detect infection even in the absence of lesions. Although Epstein-Barr virus (EBV) infections are often asymptomatic, some patients present with. Listed here are some of the most common conditions in which the diagnosis can be aided by serology studies. Lymph nodes should usually NOT be biopsied as diagnosis is clinical and serologic Atypical cases (lymphadenopathy but no fever, no sore threat, no splenomegaly) may be biopsied to rule out lymphoma Fatal cases of infectious mononucleosis are associated with monoclonal or biclonal EBV (Am J Clin Pathol 2002;117:582).

Positive results will show for the remainder of life as having had the virus. The EBV full panel contains tests for heterophile IgM antibody, VCA IgM, VCA IgG, and EBV nuclear antigen (EBNA) IgG. Accurate interpretation of EBV infection is based on results of EA(D) IgG, VCA IgM, VCA IgG, EBNA IgG, EBNA IgM and heterophile antibodies. Laboratory testing can help distinguish whether someone is susceptible to EBV infection or has a recent or past infection. Increased IgG antibodies to CMV, EBV, HHV6, Coxsackie, etc. Interpretation: The presence of antibody to early antigen (EA) of Epstein-Barr virus (EBV) indicates that EBV is actively replicating.
