Complete Blood Count (CBC)Reported in %Immature granulocytes (percent)
The share of white cells that are young granulocytes, released before they finished maturing.
What it measures
Neutrophils normally finish maturing in the marrow. Bands, metamyelocytes, and earlier forms are “immature granulocytes.” A few can appear in the blood when the marrow is answering a call. The percent says how large that early fraction is.
Why it is on the panel
It is an early-response marker. Infection and significant inflammation are the common reasons these cells show up. On a quiet screening panel the percent is usually at the floor of the interval.
How to read it
Read the percent with the absolute immature granulocyte count and the ANC. A small percent next to a high white count can still be a meaningful number of young cells. A zero result is the usual healthy finding.
When it runs higher
Bacterial infection, severe inflammation, steroid effect, and recovery from marrow suppression can raise the percent. Pregnancy can raise it modestly. A sustained or climbing result is reviewed with the rest of the CBC.
When it runs lower
The bottom of the interval includes zero. A low result is the expected one when you are well.
How to use this page
This page explains what the measurement is for. It is educational. Your Healiam report includes the reference interval for your age and sex, and a clinician reads that result with your history, medicines, and the rest of the panel. Talk with a clinician before changing diet, supplements, or treatment because of a number on a report.

One preventive draw covers this measurement and the rest of the Healiam panel. CLIA-certified results come back in days.
