Neutrophils
Neutrophils are the most common white blood cells and the first responders to bacterial infection. Labs report them as a percentage of white cells and as an absolute count; the absolute count matters more.
Your reading
This app uses 40–70%, or 1.5–7.7 thousand per microlitre. They rise with bacterial infection, inflammation, physical or emotional stress, hard exercise and steroids. Mildly low counts are common after viral infections and in some healthy people of African, Middle Eastern or Caribbean descent (benign ethnic neutropenia).
What may help
- —Repeating the test once you're well and rested
- —Looking at the absolute count rather than the percentage, which shifts when other white cells change
When to talk to a doctor
If the absolute count is below 1.0 or above 10, or you get frequent or unusually severe infections.
