Epstein-Barr virus (EBV) causes most cases of infectious mononucleosis, and the antibody pattern tells you where you are in the infection. Viral capsid antigen (VCA) IgM appears in the first weeks of a current infection and fades; VCA IgG rises during the acute phase and stays for life; and nuclear antigen (EBNA) IgG appears only weeks to months after infection, so its presence points to a past infection rather than a new one. Reading the three together — which the lab's interpretation does — separates an acute infection from a resolved one, which the quick heterophile (Monospot) screen cannot do and can miss entirely in the first week of symptoms and in children. It is the test to order when a mono screen was negative but symptoms persist, or when you need to know whether fatigue, swollen glands or a sore throat reflect a current EBV infection.
STI and infectious disease testing identifies current or past infections that often present without obvious symptoms — preventing complications, transmission, and long-term sequelae.
Anyone with a new sexual partner, symptoms suggesting an STI, recent exposure, planning pregnancy, or seeking routine sexual health screening per CDC recommendations.
