What do high levels of mono and eos in hematology results mean?

This answer was rated:

High Monos means Increased Proportion of Monocytes (in the blood). This can indicate:

- chronic inflammation
- stress response
- hyperadrenocorticism (overactive adrenal gland): RARE
- immune mediated disease
- pyogranulomatous disease
- necrosis (cell destruction)
- red cell regeneration -recent or current viral infexn. (eg. Infectious mononucleosis)

High EOS means: Increased Proportion of Eosinophil Cells in the blood:

EOS are temporarily (or chronically) increased if someone is undergoing an ALLERGIC response (eg. hay fever; food or medicine allergy; allergic rash; chemical exposure); virtually ANY type of exposure that can induce allergic response (even if youDON"T feel any sx physically, the EOS can be elevated, as a subclinical response).

I would NOT be too concerned if either level was MILDLY elevated [e.g. 1 to 4 points ABOVE normal range]; if MORE than that, however, I would call your MD to see if any further Dx tests need to be done, in order to isolate the exact cause(s).

Resolved Question:

In my Hematology test, both Mono% and Eos% were flagged as high. I wonder what this may mean.
