Immature cells/100 WBC

Immature white cells are early-stage immune cells (like bands, metamyelocytes, or myelocytes) that usually stay in the bone marrow. When your body is under stress—like infection, inflammation, or major physical strain—it may release these cells early. A small amount can be a normal response to training or illness. Persistent or high levels may signal that your immune system is working overtime.
