Leukocytosis

Leukocytosis occurs when the number of white blood cells increases above standard levels. It often resolves on its own, but, if necessary, treatment usually depends on the underlying cause. Typically, levels above 9 per liter) Trusted Source PubMed Central Highly respected database from the National Institutes of Health What is considered a high white blood cell count? A high white blood cell count is when there are more than 9 per liter) Trusted Source PubMed Central Highly respected database from the National Institutes of Health For instance, newborns have a much higher white blood count than adults. Also, people of Black African, Middle Eastern, and Caribbean descent typically have lower white blood counts than people of Hispanic or European descent. During pregnancy A person’s body undergoes a lot of stress during pregnancy, so it is common to have an elevated white blood count resulting in leukocytosis. According to a Your healthcare practitioner should be monitoring your white blood cell count throughout your pregnancy and will know if something is amiss. Causes of leukocytosis While infection, allergic reactions, or stress could cause leukocytosis, other possible causes Trusted Source PubMed Central Highly respected database from the National Institutes of Health • medications, such as corticosteroids or some common antibiotics • trauma • • chronic inflammation, such as • congenital diseases, such as Down syndrome • pregnancy • • leukemia • lymphoma • autoimmune di...

Neutrophilia happens when your body produces too many neutrophils. Neutrophils are a type of white blood cell. They help you fight infection. If there are too many neutrophils in your bloodstream, you may develop leukocytosis, or a high total white blood cell count. You may have symptoms such as fevers or recurring infections. These symptoms may be signs of an underlying condition. Symptoms and Causes What causes neutrophilia? Neutrophilia is your body’s reaction to an assortment of problems, from serious What are primary neutrophilia causes? You can be born with neutrophilia. Other causes include: • • • • Juvenile myelomonocytic leukemia (JMML). This is a rare blood cancer that typically affects children and happens when certain white blood cells don’t mature normally. • Chronic neutrophilic leukemia. This is a rare blood cancer that happens when your bone marrow makes too many neutrophils. What are secondary neutrophilia causes? Secondary neutrophilia causes are linked to various infections, inflammation caused by medical conditions and your body’s reaction to stress. Secondary causes include: • Infection and • Acute chronic inflammation that’s caused by • • Injuries such as breaking a bone. • Reactions to • Reaction to medication. • Physical or • • Vigorous exercise. What’s the difference between neutrophilia and neutropenia? What are neutrophilia symptoms? Neutrophilia itself typically doesn’t have symptoms. A high white blood cell count may be a sign of underlying con...

Medical condition Leukocytosis Leukocytosis is a condition in which the white cell ( • • • • • This increase in leukocyte (primarily neutrophils) is usually accompanied by a "left upper shift" in the ratio of immature to mature neutrophils and macrophages. The proportion of immature leukocytes increases due to proliferation and inhibition of granulocyte and monocyte precursors in the bone marrow which is stimulated by several products of inflammation including C3a and G-CSF.
