What does a low Lymphocytes mean?
Short answer
A low lymphocyte count (lymphopenia) is common and often transient — acute infections, stress, recent surgery and corticosteroids all lower it. Persistent lymphopenia is seen with HIV, autoimmune disease, malnutrition, chemotherapy and other immunosuppressants, and some marrow disorders. Below about 1.0 × 10³/µL, or with recurrent infections, it deserves a closer look.

Common questions
Can stress lower lymphocytes?
Yes — cortisol shifts lymphocytes out of the bloodstream, so acute illness, surgery and steroid medication all produce a temporary drop.
