Immature granulocytes blood test
In short
A typical adult immature granulocytes result is 0 to 0.06 x10^3/µL. A small number is common during an infection, inflammation or pregnancy and usually settles on its own. Higher or rising numbers are worth a closer look. Always read your result against the range printed on your own report.
Young white blood cells released early from the bone marrow.
Immature granulocytes are young white cells that usually stay in the bone marrow until they mature. Most healthy people have none or very few in the blood. A small number often appears while the body is fighting an infection or inflammation.

If your Immature granulocytes is high
A small number is common during an infection, inflammation or pregnancy and usually settles on its own. Higher or rising numbers are worth a closer look.
Common reasons
- A current infection, as the marrow speeds up production
- Inflammation, recent surgery or an injury
- Pregnancy, especially in the later months
- Steroid medicines, or medicines that boost white cell production
- Less often: a severe infection that has spread into the blood
- Less often: a bone marrow condition
What can throw it off
Pregnancy, a recent infection and steroid medicines can raise immature granulocytes for a while.
Questions to take to your appointment
- 1Could an infection or my medicines explain this?
- 2Should we repeat it once I'm feeling better?
- 3Do my other white cell results look settled?

What this page can’t do
It reads each number on its own.
Doctors read results together — ALT with AST, ferritin with hemoglobin, TSH with free T4. A pattern says more than any single flag.
It doesn't know you.
Your age, your medicines, how you feel and your last result all change what a number means.
It doesn't remember.
Close this page and your results are gone. That's on purpose: nothing was ever sent to us.
