Bands are immature neutrophils that are released into the blood when the body needs more infection control than mature neutrophils can provide. An elevated number of bands suggests an acute infection.
Actually the term is "blasts" Everyone has some amount of "blast" cells(immature) and they aren't ceels that can be used by the body. Elevated blast cells are a consideration when checking for diseases like Leukemia and another disease called MDS,,,Myleodysplasia. Usually if blasts are under 5%, there is no reason for great concern but you doctor will monitor that as it can develop into MDS or Leukemia, or Acute Myleoid Leukemia. If the blasts are greater 5-20% of total cell count in the bone marrow, you will probably start being treated for Leukemia. Over 20% is positive for AML..... Treatment can include Chemotherapy, Immunotherapy, Bone Marrow transplant and/or Stem cell transplant. I have AML....dealing with it just fine. It's Cancer so it is serious. Depending on your age, you may respond very will to treatment. Do not be frightened. Ask your doctor as many questions as yo9u can....they will help you.
