The reference range for<unk>  in adults varies by study, but 1500 to 8000 cells per microliter is typical. An<unk>  less than 1500 cells/µL is defined as neutropenia and increases risk of infection. Neutropenia is the condition of a low<unk> , and the most common condition where an<unk>  would be measured is in the setting of chemotherapy for cancer.<unk> ia indicates an elevated<unk> . While many clinicians refer to the presence of<unk> ia as a "left shift," this is imprecise, as a left shift indicates the presence of immature<unk>  forms, but<unk> ia refers to the entire mass of<unk> s, both mature and immature.<unk> ia can be indicative of: * Premature release of myeloid cells from the bone marrow. * A leukemoid reaction.
