What Neutrophils % measures
Neutrophils are the most common white blood cells and respond first to bacterial infections. This is their share of all white cells.
If your Neutrophils % is low
A lower share of neutrophils often means other white cells (usually lymphocytes) make up more of the total, as in viral infections.
Commonly associated with
- Viral infection
- Certain medications
- B12 or folate levels
If your Neutrophils % is high
A higher share of neutrophils is commonly associated with bacterial infection, inflammation, stress or steroid medication.
Commonly associated with
- Bacterial infection
- Inflammation
- Stress
- Corticosteroids
Typical reference range
| Group | Typical range |
|---|---|
| Adults | 40 – 74 % |
Typical adult values used by many US labs. Your own report prints the range your lab validated for its method, and that range is the one that counts. Labwise always uses the printed range first.
If it is within range
The share of neutrophils among your white cells is typical.
