Monocytes blood test
In short
A typical adult monocytes result is 0.26 to 0.81 x10^3/µL. A mildly high count is common during recovery from an infection and usually settles on its own. A count that stays high is worth a repeat test. Always read your result against the range printed on your own report.
White blood cells that clean up germs and damaged tissue.
Monocytes are white cells that move into tissues to swallow germs and clear away damaged cells. Reports give them as a count and as a percent of all white cells. A small rise is common while the body recovers from an infection.

Typical ranges for adults. Labs differ a little, so the range printed next to your result is the one to go by.
If your Monocytes is high
A mildly high count is common during recovery from an infection and usually settles on its own. A count that stays high is worth a repeat test.
Common reasons
- Recovery from an infection, often a viral one
- A high percent only, because other white cells happen to be lower
- Smoking
- Ongoing inflammation, such as from arthritis or a bowel condition
- Some longer-lasting infections, such as tuberculosis
- Less often: a blood or bone marrow condition
If your Monocytes is low
A low monocyte count on its own is uncommon and usually not a concern. It matters more when other white cells are low too.
Common reasons
- Steroid medicines, which lower it for a while
- Stress on the body, such as a severe infection or major surgery
- Chemotherapy or other treatments that slow the bone marrow
- Less often: a bone marrow condition
What can throw it off
A recent infection or steroid medicines can shift the count for a few weeks.
Questions to take to your appointment
- 1Is my absolute count off, or only the percent?
- 2Could a recent infection explain it?
- 3Should we recheck it in a few weeks?

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.
