Why is Reactive Lymphocytes important?

Reactive (atypical) lymphocytes are activated lymphocytes that appear larger and more irregular than normal lymphocytes. In functional medicine, reactive lymphocytes indicate active immune response to infections, particularly viral infections like EBV, CMV, or other viruses. Their presence suggests ongoing immune activation and can help identify viral infections versus bacterial infections. Persistent reactive lymphocytes may indicate chronic viral infections or ongoing immune stimulation.

What are the symptoms of abnormal Reactive Lymphocytes levels?

Reactive lymphocytes often accompany viral infection symptoms: fatigue, swollen lymph nodes, sore throat, fever, or chronic fatigue.
