See a healthcare professional for evaluation
Get a physical exam
Ask about symptoms such as fever, sore throat, swollen glands, and fatigue
Have a rapid strep test or throat culture to rule out strep throat
Get a monospot test to check for heterophile antibodies
Get an Epstein-Barr virus antibody blood test if the monospot test is negative or unclear
Get a complete blood count to look for atypical lymphocytes
Follow any additional testing your clinician recommends if symptoms are severe or unusual
