Metamyelocytes (Absolute) Unit Converter

Metamyelocytes are immature white blood cells that belong to the granulocyte family, the same lineage that produces neutrophils. They represent an intermediate stage of development between myelocytes and band neutrophils.

Under normal circumstances, metamyelocytes remain in the bone marrow until they fully mature. The absolute metamyelocyte count measures the number of these immature cells circulating in peripheral blood per unit volume.

A normal result is zero. Any detectable metamyelocytes in the bloodstream indicate that the bone marrow is releasing cells before they are fully mature, a phenomenon known as a "left shift."

Metamyelocytes are produced in the bone marrow as part of the normal maturation sequence of granulocytes (neutrophils, eosinophils, and basophils). They develop from myelocytes and normally mature into band cells before being released into the bloodstream.
