Monocytes (Mono%)

Monocyte percentage of total white cells.

What it is

Normal monocyte percentage is 2–10% of total white blood cells. Used alongside other differentials to characterise the immune profile.

Why it matters

Persistently elevated monocyte percentage (monocytosis) can be a clue to chronic inflammation or specific haematological conditions. Trends within your treatment context are more informative than single values.
