Shows what share of your white blood cells are neutrophils, key fighters against infection.
This is the share of your white blood cells that are neutrophils, given as a percentage. Neutrophils are the immune cells that move fast to fight bacteria and fungi.
The percentage comes from the differential part of a complete blood count. It is most useful read next to the absolute neutrophil count.
A raised neutrophil percentage often goes with bacterial infection, inflammation, or physical stress. A low percentage can follow some viral infections or certain medicines. On its own a percentage can mislead, because it shifts when other cell types rise or fall, so it is read together with the absolute count.
Aniva reads your result against research-backed ranges, not just the lab's wide normal. The reference shown below is specific to this biomarker.
Typical adult range, automated differential:
| Measure | Typical range |
|---|---|
| Neutrophils, percent of WBC | 40 to 75 % |
Ranges are guidance only and vary by laboratory and analyser. Read against your lab's own reference range, aligned to German practice (DGKL).
You learn what proportion of your white cells are neutrophils. Combined with the absolute count and the rest of the differential, it helps point toward infection, inflammation, or an immune shift worth a closer look.
The percentage moves when any other white cell type rises or falls, so it can look abnormal even when neutrophils themselves are normal. Stress, exercise, smoking, steroids, and recent infection all shift it. Delays before analysis can affect the result.
Best read with the absolute neutrophil count and the other differential percentages, since they all add up to 100 percent of the white cells.
What does a high or low Neutrophils % mean? High often points to infection, inflammation, stress, or steroid effects. Low can happen with some viruses, certain medicines, or bone marrow issues.
Do I need to fast for this test? No. You can eat and drink normally unless your clinician advises otherwise.
What can affect my results? Recent illness, hard exercise, smoking, dehydration, and medicines like steroids or chemotherapy can change the percentage.
How often should I test it? Most people test only when symptoms or treatments warrant. Your clinician may repeat it to confirm changes or track recovery.
How long do results take? Results are usually ready in about 7 days.
What should I discuss with my clinician? Share recent symptoms, infections, vaccines, and all medicines or supplements. Ask whether the absolute neutrophil count adds helpful context.
