Epsien-barr capsid antigen IgM
The Epstein-Barr Virus (EBV) belongs to the herpes virus family and is responsible for causing glandular fever. After infecting an individual, EBV persists in the body for the rest of their life, often without any noticeable symptoms, except in cases where the immune system is weakened, causing the virus to reactivate. EBV spreads through saliva, and it is estimated that approximately 95% of people in the UK will have been infected with the virus by the time they reach 40 years of age.
