What does IgG positive and IgM negative mean in an EBV test?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hi doctor,

I recently got an EBV test done. My result was IgG positive and IgM negative. What does this mean? Is it life-threatening, like HIV? Is it contagious? Please guide

Hi,

Welcome to icliniq.com. IgM (immunoglobulin M) negative and IgG (immunoglobulin G) positive means that you do not have an acute infection but may be a carrier of Epstein-Barr virus (EBV) which is not as dangerous as HIV (human immunodeficiency virus) and can be easily treated. You may develop symptoms of sore throat, swollen glands, fever, rashes, abdominal pain, cough, and runny nose. Symptoms generally last for between a week and a month, although they can recur when the body is under stress. EBV is contagious and spreads via saliva, often through kissing, sharing of drinks, eating utensils, toys, towels, etc. Treatment in children includes rest and plenty of fluids. Painkillers are usually prescribed to relieve fever and pain. If there is extensive swelling of the throat or glands which compromise breathing, then steroids may be given.

Patient's Query

Hello doctor,

Your answer relieved me. Thanks a lot, doctor. Does this EBV disappear after medication, or does it remain forever? Should I never kiss anyone in my life?

Hi,

Welcome back to icliniq.com. Since it is a self-limiting disease, it will get over in a month or a maximum of up to six months in some resistant cases. I would suggest you avoid kissing till antibody titers become negative.
