Myelocytes/100 WBC (Bld)

Myelocytes are early-stage white blood cell precursors that normally mature inside the bone marrow. If they’re showing up in your blood, your immune system is likely in emergency mode—pushing out immature cells in response to severe infection, trauma, systemic inflammation, or bone marrow dysfunction. This is an advanced stress signal, often accompanying other immature cells like bands or metamyelocytes.
