Neutrophils %
Understand Neutrophils percentage for acute infection and immune function assessment. Monitor first-line immune response patterns.
What is Neutrophils Percentage?
Neutrophils percentage represents the proportion of neutrophils among all white blood cells. Neutrophils are the most abundant white blood cells and serve as the body’s primary defense against bacterial infections and acute inflammation.
Why is it Tested?
Doctors use neutrophil percentage to evaluate immune system function, diagnose bacterial infections, assess bone marrow disorders, and monitor treatment response. It helps distinguish between bacterial and viral infections and guides antibiotic therapy decisions.
Normal Ranges
Reference ranges for neutrophil percentage:
- Normal: 40–70%
This represents the typical proportion of neutrophils in a healthy adult’s white blood cell differential count.
Reference ranges vary by authority. Track yours across multiple standards with automatic unit conversions in LabsVault.
What do Abnormal Results Mean?
Abnormal results are not a diagnosis. Always discuss your results with a qualified healthcare provider before making any medical decisions.
Low Neutrophil Percentage
Reduced percentage may indicate:
- Viral infections
- Autoimmune disorders
- Bone marrow suppression
- Certain medications
- Nutritional deficiencies
High Neutrophil Percentage
Elevated percentage suggests:
- Bacterial infections
- Inflammatory conditions
- Physical or emotional stress
- Smoking
- Some medications (corticosteroids)
- Tissue necrosis or burns
How to Track Over Time
Neutrophil percentage helps monitor infection progression and treatment effectiveness. During bacterial infections, rising percentages may indicate worsening infection, while declining percentages suggest successful treatment. Persistent abnormalities may warrant further investigation for underlying conditions.
