A differential informs the healthcare provider as to which type of WBC is low or high. The next step is migration diapedesis through the vascular matrix.

Neutrophilia is also seen with furuncles, abscesses, tonsillitis, appendicitis, otitis media, osteomyelitis, cholecystitis, salpingitis, meningitis, diphtheria, plague, and peritonitis. Infections such as typhoid fever, parathyroid fever, mumps, measles, and tuberculosis usually are not associated with leukocytosis. In noninfectious conditions, such as burns, a postoperative state, acute asthma, [ 3 ] myocardial infarction, acute attacks of goutacute glomerulonephritis, rheumatic fever, collagen-vascular diseases, hypersensitivity reactions, and even cigarette smoking, neutrophilia can occur.

Neutrophilia in severe burns is accompanied by a shift to the left in the differential and the presence of degenerative forms, including toxic granulation and Dohle bodies. Postoperatively, neutrophilia occurs for hours as a result of tissue injury—related increases in adrenocortical hormones. Leukocytosis can also occur in intestinal obstruction and strangulated hernia. Neutrophil activation during cardiopulmonary bypass CPB surgery may occur because of the release of complement chemotactic products or the local release of interleukin IL The expression of beta-2 integrins on the neutrophil of neutrophils is increased in response to IL-8 and to what components of complement during CPB.

Patients with acute myocardial infarction experience a transient but significant rise in serum IL-8 concentration within 24 hours after the onset of symptoms. Thus, IL-8 is likely involved in the pathogenesis of myocardial injury following coronary artery bypass graft CABG surgery. Neutrophilia commonly occurs in cases of diabetic ketoacidosis, preeclampsiaand uremiaespecially with uremic pericarditis.

Neutrophilia can result from poisoning with lead, mercury, digitalis, camphor, antipyrine, phenacetin, quinidine, pyrogallol, turpentine, arsphenamine, and insect venoms. Acute hemorrhage, especially into body spaces such as the peritoneal cavity, pleural cavity, joint cavity, and intracranial cavity e. Local inflammation due to pressure necrosis and the generation of chemotactic bloods from the lysis of leukocytes high contributes.

During the first hours of an acute hemorrhage, neutrophilia occurs because of a shift from the marginal result to the circulating pool. After hours, neutrophils are released from the marrow.

Acute hemolysis leukocytosis occurs following a transfusion of mismatched blood or during acute hemolytic disease. Chronic myelocytic leukemia, polycythemia vera, myelofibrosis, and myeloid metaplasia result in neutrophilia. This process is thought to be due to tumor necrosis factor TNF -alpha. Some tumor types produce neutrophilic growth factors eg, granulocyte colony-stimulating factor [G-CSF] production by squamous cell cancers of the head and neck. Strenuous exercise and epinephrine injection can cause transient neutrophilia.

Physiologic neutrophilia is also seen in pregnancylabor, and in newborns. Hereditary neutrophilia has been described. Neutrophilia can occur with anemia eg, in chronic infectionspolycythemia polycythemia veraincreased platelet count essential thrombocythemiadecreased platelet count sepsisand nucleated RBCs myelofibrosis, malignancies. Short- or long-term administration of corticosteroids causes neutrophilia.

Neutrophilia is seen in association with Cushing disease.

Neutrophilia may be present without an identifiable cause; in this case, it is known as chronic idiopathic neutrophilia. Hematopoietic stem cells are pluripotent cells that are capable of self-replication and differentiation.

Committed stem cells capable of developing into myeloblasts are formed from the multipotent hematopoietic stem cell. The first 3 morphologic stages in the development of mature neutrophils are capable of replication. Later stages of neutrophil development only undergo cell differentiation. The representative cells in the first 3 stages are myeloblasts, promyelocytes, and myelocytes. The myeloblast cell has a large nucleus, is round or oval, and has a small amount of cytoplasm.

No condensation of chromatin is observed, and nucleoli are present. No granules are present in the cytoplasm at this stage. The promyelocyte cell is larger than the myeloblast. The nucleus is round or oval, and the nuclear chromatin is diffuse, as in the myeloblast. The nucleoli tend to become less prominent as the cell develops.

WBC Differential

The azurophilic or primary granules appear at this stage, but the secondary granules are not yet present. The primary granules are budded off the concave surface of the Golgi complex. In the myelocyte stage, the secondary granules appear. These granules are smaller than the primary granules and stain heavily for glycoprotein.

A pinkish ground-glass background, which is the glycoprotein, is observed when the cell is stained. Secondary granules arise from the convex surface of the Golgi complex. The myelocyte nucleus is eccentric and round or oval.

Blood differential test

The nuclear chromatin is coarse. The nucleoli are smaller and less prominent in the myelocyte stage when compared with the promyelocyte stage. Primary granule formation is limited to the promyelocyte stage. With each subsequent cell division, the number of primary granules decreases. In mature neutrophils, the ratio of secondary granules to primary granules in humans is approximately The next stage, the metamyelocyte stage, is characterized by an indented or horseshoe-shaped nucleus without nucleoli.

Some symptoms of acute kidney failure include confusion, fatigue, shortness of breath, drowsiness, fluid retention and decreased urine output.

Eclampsia Although rare, eclampsia can be very serious. Medication Effects Some specific medications can also be a cause of high neutrophils.

Lithium carbonate is one medication that can increase the count. This is a form of salt that is used as a prescription to help reduce the effects of mania an overly excited state. Another medication that can increase your neutrophils count is corticosteroids.

These are a type of drugs that mimic the effects of corticosteroid hormone, a natural chemical found in the body. These hormones help control how our body uses nutrients as well as the quantities of salt and water in the urine.

Other Causes Ketoacidosis is another possible cause of high neutrophil counts.


When someone suffers from this condition the body produces ketones poisonous chemical substances and acids. This condition is a medical emergency and requires hospitalization so fluids can be given by vein and drugs to reduce the white blood cell count hydroxyurea and chemotherapy drugs can be given. Sometimes, a type of blood-filtering treatment leukapheresis is used to remove the white blood cells from the blood. Tap to switch to the Professional version. Additional Content Medical News.

Neutropenia Was This Page Helpful? Neutropenia, or a low neutrophil count, can last for a few weeks or it can be chronic. It also can be a symptom of other conditions and diseases, and it places you at greater risk for acquiring more serious infections. If abnormal neutrophil counts are due to an underlying condition, your outlook and treatment will be determined by that condition. If your doctor orders a CBC with differential or an ANC screen, you may find it useful to ask the following questions. Let us know how we can improve this article.
