Eosinophils (percentage)
Eosinophils (percentage) tell the PERCENTAGE of white blood cells that are eosinophils (allergic/parasitic cells). For assessment the absolute count is often more important.
Ranges we use
| Rating | Range | What it means |
|---|---|---|
| Good | below 6 % | Within the reference range. |
| Worth improving | 6 % and above | Elevated eosinophils — often allergy or a parasite; context and repeat testing. |
Range: reference interval set by the laboratory (method-dependent) — the app uses the range printed on your report.
Why it matters
Elevated often with allergies, asthma, or parasites; markedly elevated requires evaluation.
If it’s low
A low percentage is mostly insignificant.
If it’s high
A high percentage of eosinophils accompanies allergies, drug reactions or parasites.
