Neutrophilic Leukocytosis
Diagnosis of Neutrophilic Leukocytosis
Blood tests Doctors often do a blood test called a complete blood count. This test may be done for many different symptoms, including signs of infection (such as fever, cough, or abdominal pain), or signs of chronic illness (such as weight loss or fatigue). If doctors discover an increased number of neutrophils and there is no clear reason, such as an obvious infection, a blood sample is viewed under a microscope to determine if immature neutrophils (myeloblasts) are leaving the bone marrow and entering the blood. Immature neutrophils in the blood may indicate the presence of a disorder in the bone marrow, such as leukemia. When immature neutrophils are found in the blood, doctors usually take a sample of bone marrow ( Bone Marrow Examination ).
