The metamyelocyte percentage is measured to assess how many immature white blood cells (specifically, metamyelocytes) are present.
This helps doctors understand if the bone marrow, where blood cells are made, is functioning properly. High levels of these immature cells can indicate infections, inflammation, or bone marrow disorders, including leukemia.
Monitoring the percentage of metamyelocytes is useful for diagnosing and tracking the progress of diseases affecting blood cell production and overall immune function. This measurement provides crucial information to guide treatment decisions and monitor a patient’s response to therapy.
