What is MO on complete blood count?

MO on a complete blood count (CBC) typically refers to monocytes, which are a type of white blood cell involved in the immune response. They help to fight infections by engulfing and destroying pathogens and also play a role in inflammation and tissue repair. An elevated or decreased monocyte count can indicate various conditions, including infections, inflammatory diseases, or hematological disorders. Typically, monocyte levels are reported as a percentage of the total white blood cell count.
