High Monocytes (MON): Understanding a Blood Count

Overview

Monocytes are white blood cells that support immune defence. A percentage or absolute monocyte result on a blood count cannot by itself establish a diagnosis.

How should results or symptoms be assessed?

Recovery from infection, ongoing inflammation and occasionally blood disorders can be associated with an increased count. The absolute number, other blood cells and the trend over time matter.

Practical next steps

Compare current and earlier blood counts. Report prolonged fever, night sweats, weight loss or persistent enlarged lymph nodes to your clinician.

When is medical help needed?

Severe illness with high fever, breathlessness or altered consciousness needs urgent evaluation.

Frequently asked questions

Can this article establish a diagnosis or treatment?

No. An individual history, examination and sometimes further tests are needed.

What should I prepare for a consultation?

Note when symptoms began, past reports, your medicines and questions so you can discuss them clearly.

Online advice cannot replace an in-person examination when one is required.
