A positive IgG for EBV suggests a previous infection with EBV, while a negative IgM suggests that EBV is not present in the body at the present time. The EBV test generally includes IgG and IgM, and the IgG result can be used to determine the status of previous infections. If IgG is positive, it indicates that the patient has been infected with EBV. The current infection can be determined by the IgM result. If there is no IgM antibody after the test and the result is negative, it indicates that there is no EBV currently present in the patient’s body. The EB virus, also known as the human herpes virus, has been linked to malignant lymphoma and infectious mononucleosis in African children. If a diagnosis of EBV infection is confirmed, it is best to get prompt and relevant treatment.
