What does mono percent mean in blood count?

Mono percent, or monocyte percentage, refers to the proportion of monocytes in a complete blood count (CBC). Monocytes are a type of white blood cell that plays a key role in the immune system by helping to fight off infections and remove dead or damaged cells. A normal monocyte percentage typically ranges from about 2% to 8% of the total white blood cell count. Abnormal levels can indicate various health conditions, including infections, inflammatory diseases, or blood disorders.
