Clinicians order neutrophil testing to check for infection, inflammation, or how well the bone marrow is making white cells. It’s usually part of a complete blood count with differential and is helpful if you have fever, sore throat, or are on treatments that affect immunity, like chemotherapy. Results can guide follow-up such as a repeat test, blood smear, cultures, or a medication review. You can test this marker with Aniva across Germany and Finland.

High: Often rises with bacterial infection, inflammation, stress, steroid use, smoking, or vigorous exercise. Usually short-lived; your symptoms and trends guide next steps.
Low: Can happen with viral illness, certain medicines, autoimmune conditions, vitamin deficiencies, or chemotherapy. Lower counts may raise infection risk; confirm with ANC and consider a repeat test. Looking at other white cell types adds helpful context.

• White blood cell count
• Lymphocytes
• Monocytes
• Eosinophils
• Basophils
• CRP

Common factors that can shift results include recent infection, surgery, or trauma; vigorous exercise; smoking; stress; pregnancy; dehydration; and time of day. Medicines can raise counts (steroids, beta-agonists, lithium) or lower them (chemotherapy, clozapine, antithyroid drugs). Delays in processing or poor sample handling can also skew counts.

Special situations: if you’re on chemotherapy, immunosuppressants, or have severe symptoms, confirm with a repeat ANC and discuss timing with your clinician.
