The increase of band cells in the circulation is called bandemia and is a "left shift" process. Blood reference ranges for neutrophilic band cells in adults are 3 to 5% of white blood cells, [3] or up to 0.7 × 10 9 /L. [4] An excess may sometimes be referred to as bandemia.
Bandemia refers to an excess or increased levels of band cells (immature white blood cells) released by the bone marrow into the blood.It thus overlaps with the concept of left shift—bandemia is a principal type of left shift and many (perhaps most) clinical mentions of the latter refer to instances of this type.
A metamyelocyte is a cell undergoing granulopoiesis, derived from a myelocyte, and leading to a band cell. It is characterized by the appearance of a bent nucleus, cytoplasmic granules, and the absence of visible nucleoli. (If the nucleus is not yet bent, then it is likely a myelocyte.)
Conventionally, a leukocytosis exceeding 50,000 WBC/mm 3 with a significant increase in early neutrophil precursors is referred to as a leukemoid reaction. [2] The peripheral blood smear may show myelocytes, metamyelocytes, promyelocytes, and rarely myeloblasts; however, there is a mixture of early mature neutrophil precursors, in contrast to the immature forms typically seen in acute leukemia.
It should increase within 2–3 days of a major acute hemorrhage, for instance, and reach its peak in 6–10 days. [3] If reticulocyte production is not raised in response to anemia, then the anemia may be due to an acute cause with insufficient time to compensate, or there is a defect with red blood cell production in the bone marrow.
Reactive lymphocytes were originally described by W. Türk in 1907 in the peripheral blood of patients with infectious mononucleosis.Later in 1923 the features of the reactive lymphocytes were characterized in greater detail by Hal Downey and C.A. McKinlay, who also discovered the association with EBV and CMV.

Giemsa stain (/ ˈ ɡ iː m z ə /), named after German chemist and bacteriologist Gustav Giemsa, is a nucleic acid stain used in cytogenetics and for the histopathological diagnosis of malaria and other parasites.
