I don't fully understand EBV, as this has more antibody tests than other viruses. With other viruses, antibody tests are usually just for IgM and IgG.
IgM are the first antibodies the immune system makes when you first catch an infection. IgG antibodies are made slightly later, and they become the long-term antibodies that stay in your blood, to help protect you from a reactivation of the same virus.
