What Is Mononucleosis?
9. Diagnosis
In many cases, your doctor will be able to diagnose mono from a physical exam. In particular they are likely to look for swollen lymph nodes, and other symptoms such as swollen tonsils. The symptoms of mono are not usually serious and it is not usually considered necessary to investigate further.
In some cases, however, it might be deemed necessary to confirm the diagnosis. In which case, blood samples are likely to be taken so they can then be sent to a laboratory for analysis. A monospot is another test that can be used specifically for mono, but it might miss the disease in the first week after infection.
