In a blood test, "MO" typically refers to monocytes, a type of white blood cell. The test might report absolute monocytes (MO, abs), representing the total number of monocytes, or percentage monocytes (MO, pct), showing the monocytes' proportion within the total white blood cell count.
Understanding Monocytes
Monocytes are crucial components of your immune system. They are large white blood cells that fight off infections and diseases, including cancer. A blood test measuring monocyte levels helps monitor your immune system's health and overall blood health. Cleveland Clinic provides further information about monocytes and their function.
Interpreting MO Results
A complete blood count (CBC) includes the measurement of monocytes. The results, whether absolute or percentage, will be compared against normal ranges to determine if the count is within the healthy range or indicates a potential issue. An elevated monocyte count (monocytosis) might suggest an infection, an autoimmune disorder, or a blood-related problem. Verywell Health discusses the significance of high monocyte counts. Conversely, a low count could indicate other health conditions. Always consult your doctor to understand the meaning of your specific results within the context of your overall health.
How Monocytes are Measured
Your doctor orders a blood test to measure your monocyte levels. A blood sample is taken, and the lab analyzes it to determine the number or percentage of monocytes present. This is part of a broader white blood cell count that identifies the five different types of white blood cells. IWMF provides a chart summarizing a CBC blood test including monocytes.
