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 Bone Marrow Examination Red blood cells, most white blood cells, and platelets are produced in the bone marrow, the soft fatty tissue inside bone cavities. Sometimes a sample of bone marrow must be examined to determine An increased number of mature neutrophils in the blood is not usually a problem in itself.
Therefore, doctors focus on treating the condition or disorder that caused the number of neutrophils to increase. Merck and Co. From developing new therapies that treat and prevent disease to helping people in need, we are committed to improving health and well-being around the world.

Common Health Topics. Hyperviscosity syndrome. The lower blood level limit for neutrophils in human blood is 1, per mm3. The lower the level of neutrophils circulating in the blood, the more severe neutropenia. Neutropenia levels are:. Minor changes in neutrophil or white blood cell levels are typically nothing to worry about as long as they are temporary. A raised white blood cell count often means the body is responding to infection, injury, or stress.
Some people have naturally lower levels of white blood cells and neutrophils than other people due to a range of factors, including congenital conditions. If neutrophil or white blood cell levels are significantly altered for no apparent reason or remain raised or lowered, a doctor will order more tests to determine the cause.
Severely high or low levels of white blood cells often require emergency care and monitoring. People with severe neutropenia will have an inadequate defense against infection.
People with severe neutrophilia typically have a life-threatening type of infection or other inflammatory illness that requires treatment, such as cancer. Antibiotics can treat bacterial infections, while antifungal medicine treats fungal infections. People can treat certain viral infections with medications that slow viral activity.
Otherwise, supportive therapies, such as fluids and rest, may be part of the treatment plan. People with altered neutrophil levels caused by medications or procedures may need to stop or adjust treatments. People with chronic conditions that disrupt adequate neutrophil production or maturation may need to take drugs that allow the body to raise neutrophil production, such as:. People with severely low levels of neutrophils often require monitoring, antibiotic therapy, and hospitalization to reduce the risk of severe infection.
This period of intensive care helps keep people with weakened immune systems away from potentially harmful microorganisms. It also supports the body, giving it time to produce more white blood cells.
One of the causes of low neutrophil blood levels is a vitamin B deficiency. Eating foods rich in B may help improve low neutrophil blood levels. Examples of foods rich in vitamin B include:.
To help reduce the risk of high or low neutrophil levels, people may want to try the following tips:. However, people with only minor or mild changes in their neutrophil blood levels often show no symptoms and do not require any treatment. Having a healthy number of neutrophils in the blood and bone marrow is crucial to the correct working of the immune system. When neutrophil levels are higher or lower than usual for more than a short period, a doctor will order several tests to work out the underlying cause.
People with significantly altered neutrophil levels may also require hospitalization to prevent infection and treat life-threatening conditions. Anyone with concerns about their neutrophil count or any medical condition should talk to their doctor who will be able to answer questions they may have. Antibiotics include a range of powerful drugs that kill bacteria or slow their growth. They treat bacterial infections, not viruses. If used…. Low neutrophil counts are most often associated with medications but they also can be a sign of other factors or illness, including:.
Very low neutrophil counts can lead to life-threatening infections. If your neutrophil counts are high, it can mean you have an infection or are under a lot of stress. It can also be a symptom of more serious conditions. 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. A complete blood count, or CBC, measures several components of your blood and can help diagnose a broad range of conditions, from anemia and to cancer.
White blood cells, or WBCs, are an important part of your immune system. They help fight infections by attacking bacteria, viruses, and germs. A blood differential test, also known as a white blood cell count differential, measures the number of different types of white blood cells in your….
Lymphocytes are white blood cells. Your lymphocyte counts can help your doctor diagnose an infection or other condition. An eosinophil count is a type of blood test that measures the quantity of eosinophils in your body. An eosinophil is a type of white blood cell. Basophils are a type of white blood cell. White blood cells work to keep you healthy by fighting off viruses, bacteria, and fungi. Learn more.
