Can this result diagnose a condition on its own?

No. A laboratory result should be interpreted with related tests, symptoms, medical history, and the reference information on the report.

Which reference range should I use?

Use the reference interval provided by the laboratory that performed the test. Clinical decision cutoffs, when relevant, are shown separately.

When should I discuss the result with a healthcare professional?

Professional assessment is appropriate when a result is markedly outside the reference interval, serious symptoms are present, an abnormality persists or recurs, or follow-up has been recommended.

Information about a laboratory test

Neutrophils: What Does This Blood Test Measure?

Shows the percentage or absolute number of neutrophils, one of the most common types of white blood cell.

Test summary

Test name: Neutrophils
Abbreviations: NEU, NEUT, ANC
Category: Hematology / Immunology
Panel: WBC Differential / Hemogram
Specimen: Whole blood
Common units: %, /µL, x10^9/L

What does the test measure?

Shows the percentage or absolute number of neutrophils, one of the most common types of white blood cell.

Why is the test ordered?

Used with the total WBC count and other white-cell subtypes, especially when evaluating infection and immune responses.

Information about a low result

A low neutrophil count may increase susceptibility to infection and can be associated with bone-marrow conditions, medicines, chemotherapy, or some infections.

Information about a high result

A high neutrophil count may be associated with infection, inflammation, physical stress, or certain medicines.

Reference and clinical context

Use the reference interval printed on your own laboratory report first. Reference intervals may vary by laboratory, method, unit, age, sex, pregnancy, specimen, and other conditions. Numeric records in this workbook are explicitly labeled as either source-based example reference intervals or clinical decision cutoffs.

Reference range 1

>= 40 – <= 60 %

Population: General
Specimen: Whole blood

Example differential percentage

MedlinePlus example differential percentage; absolute counts and lab-specific ranges may be more relevant.

Reference ranges may vary by laboratory, method used, age, sex, pregnancy status, and clinical context. The reference range on your own laboratory report takes precedence.

Interpretation notes

In some clinical situations, the absolute neutrophil count (ANC) is more informative than the percentage. The format used by the laboratory should be considered.
