About Lymphocytes
Lymphocytes are a type of white blood cell that plays a crucial role in the immune system, responsible for producing antibodies and other substances that fight infection and disease. They are primarily involved in the body's adaptive immune response and include B cells, T cells, and natural killer cells.

Health Implications
High
Elevated levels may indicate a viral infection or the presence of certain autoimmune disorders that cause an immune system overreaction.
Low
Low levels may be associated with a weakened immune system, making individuals more susceptible to infections and possibly indicating conditions like HIV/AIDS or damage to bone marrow.
Symptoms
High
May include fatigue, swollen lymph nodes, unexplained weight loss, persistent or recurrent infections, fever, or night sweats.
Low
Can include dizziness, shortness of breath, fatigue, paleness, recurring infections, or general weakness.
