Clinicians order a lymphocyte count as part of a complete blood count to check immune activity. It helps explore infections, inflammation, and some blood disorders, and to monitor medicines that affect white cells. It’s useful if you have frequent infections, swollen lymph nodes, or are using steroids, immunosuppressants, or chemotherapy. You can test this marker with Aniva across Germany and Finland.

High: Can rise with viral infections, chronic inflammation, smoking, or certain blood conditions. Levels may also bump up after stress or hard exercise.
Low: May occur with acute illness, corticosteroids, chemotherapy, autoimmune conditions, or poor nutrition. Lower levels can increase infection risk.
Review recent illnesses and medications, and consider retesting when you’re well for a clearer picture.
Common factors can shift results: recent infections or vaccines, corticosteroids, immunosuppressants, chemotherapy, smoking, intense exercise, stress, dehydration, pregnancy, and mild day–night variation. Delayed sample processing may affect the differential.
Special situations: after major illness, during pregnancy, or while on immune‑modifying therapy, confirm or adjust timing with a repeat test guided by your clinician.
What does my lymphocyte result mean? It reflects how active your immune system is. Higher levels often suggest an immune response; lower levels suggest fewer immune cells.
Do I need to fast for this test? No. Lymphocyte testing does not require fasting.
What can affect my levels? Recent infections or vaccines, steroids, immunosuppressants, chemotherapy, smoking, stress, and hard exercise can all shift results.
How often should I test? Usually during routine checkups or as your clinician recommends. Retest after illness or medication changes for clearer trends.
How long do results take? Most labs report within 1–2 business days.
What should I discuss with my clinician? Share symptoms, recent illnesses or vaccines, all medications and supplements, and any smoking or exercise habits.
