The percentage of immature white cells, a sign of active infection or inflammation.
Immature granulocytes percent expresses the young, not yet mature neutrophil-family white cells as a share of all white blood cells. It is the same measurement as the absolute immature granulocyte count, just reported as a percentage of the total.
Haematology analysers calculate it automatically during the complete blood count differential. In a healthy person it sits very close to zero.
A rising percentage shows the bone marrow is pushing out young white cells faster than usual, most often because of infection or inflammation. As a proportion, it puts the immature cells in the context of the whole white cell population.
Higher values are linked to bacterial infection, sepsis, tissue damage and recovery after surgery. Like the absolute count, persistently high results are checked against the wider blood 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 guidance, analyser dependent:
| Result | Range |
|---|---|
| Immature granulocytes (%) | 0.0 to 0.5 % |
Values near zero are normal. Cut-offs differ between analysers and labs, so read your result against your laboratory's reference interval.
The percentage can rise slightly in pregnancy and after surgery without underlying disease. Old or clotted samples reduce accuracy, and very low numbers make the percentage less reliable. A blood film confirms persistently high results.
Read alongside the absolute immature granulocyte count, total white cells, neutrophils, and C-reactive protein.
