Epstein-Barr Virus — The Kissing Disease Detective
Ever had a bout of tiredness so deep it felt like your body just forgot how to function? That might have been EBV. Epstein-Barr virus is ridiculously common — most adults have had it at some point. It's the culprit behind glandular fever (mono), and it spreads mainly through saliva. The thing is, many people carry it without a clue. This test checks for IgM antibodies (active infection) and IgG antibodies (been there, done that, got the immunity).
Why Test Epstein-Barr Virus (EBV)?
Still dragging yourself through the day with a sore throat, swollen glands, and fatigue that just won't budge? This test can tell you if EBV is behind it. It's also useful if you want to know whether you've already had it, need to rule out other causes of chronic tiredness, are being evaluated for chronic fatigue syndrome, or are planning a pregnancy and want to check your immunity.
What Do High Epstein-Barr Virus (EBV) Levels Mean?
Positive IgM means you're in the thick of an active infection — expect fever, sore throat, and a strong desire to sleep for a week. Positive IgG alone? That's just your immune system's receipt showing it handled EBV in the past. If both are positive, you're likely in the recovery lane of a recent infection.
What Do Low Epstein-Barr Virus (EBV) Levels Mean?
Negative on both IgM and IgG? You've never met EBV — which means you could still catch it. The most common pattern in adults is negative IgM with positive IgG: past infection, current immunity. Nothing to worry about.
