The identification of mature and immature blood cells in peripheral blood smears and bone marrow preparations is fundamental to the laboratory diagnosis of haematological disorders. Here, you may review the mature and immature white cells to gain more practice and confidence in their identification.
Bands are slightly immature white blood cells. By itself, high band count does not need treatment, the cause of high band count needs to be ascertained and treated. When the bone marrow accelerates the production of white blood cells, usually in response to an infection, slightly immature white blood cells are released into circulation.
