Segmented neutrophils are a bunch of cells of the immune system involved in protecting the body against foreign agents. Measuring their level is helpful in medical diagnostics.
White blood cells or leukocytes are immune cells involved within the defense and protection of the human body. This family includes neutrophils, basophils, eosinophils, lymphocytes and monocytes. But what are segmented neutrophils?
Neutrophils along with basophils and eosinophils form a bunch of leukocytes called granulocytes Or polymorphonuclear cells (PMN). Studies estimate that they’re the fundamental phagocytic cells within the blood and make up 50% to 70% of all white blood cells.
What are segmented neutrophils?
Neutrophils are considered the primary line of cellular defense against germs and foreign bodies. They are formed within the bone marrow within the technique of the so-called phagocyte poetry. They then pass into the bloodstream, completing a half-life of two to three days.
There are two types of neutrophils within the human body. The mature variant is segmented neutrophilsacting directly within the tissues, fighting infections.
On the opposite hand, striated neutrophils are the immature form that accumulates within the bone marrow as a reserve. Similarly, one of these neutrophil tends to extend its presence within the blood within the presence of an infectious technique of bacterial origin.
How are they measured and what are the conventional values?
Neutrophil levels are determined by white blood cell differentiation as a part of a whole blood count (CBC). This test is performed on a fingertip or venous blood sample.
The collected blood sample is inserted right into a machine called a hematology analyzer. It has the power to discover, classify and count each of the cells that make up the blood.
The normal concentration of leukocytes within the blood is generally between 4,500 and 11,000 cells per microliter of blood. From this result, it is feasible to acquire a differential count of every of the sorts of white blood cells that make up this group.
Normal blood segmented neutrophil values range from 1,800 to 7,700 cells per microliter. This takes under consideration the proven fact that neutrophils make up 50% to 70% of white blood cells, as already highlighted.

When do segmented neutrophil values change?
The segmental neutrophil count is useful in identifying acute or chronic diseases that threaten the health of the body. High neutrophils indicate infectious processeswhile a reduced variety of neutrophils is related to a malfunctioning immune system.
Elevated neutrophils
An increase within the concentration of neutrophils within the blood known as neutrophilia. Tests states that it’s defined as an absolute neutrophil count greater than 7,500 cells per microliter of blood.
Some of essentially the most common causes of high segmented neutrophil values are as follows:
- Eclampsia
- Burns
- Intense exercise
- Bacterial infections
- Liver damage and necrosis
- Acute hemorrhage
- Emotional and metabolic stress
- Inflammatory disorders resembling rheumatoid arthritis or gout
Other less common causes include myeloproliferative syndromes, chronic myelogenous leukemia, metastatic infiltrates, and myelofibrosis. A neutrophil count above 50,000 cells per microliter known as leukemic response and could be seen in whooping cough and infectious mononucleosis.
Low level of neutrophils
A reduced level of neutrophils known as neutropenia and occurs when the variety of cells drops below 1,500 per microliter of blood. Neutropenia could be mild, moderate or severe and carries a high risk of infection.
Typical causes include:
- Aplastic or megaloblastic anemia
- Chemotherapy or radiotherapy
- Autoimmune diseases
- HIV/AIDS
- Sepsis
- hypersplenism
- Hypothyroidism
- Myelofibrosis
- Cirrhosis

When to hunt medical attention?
A change within the variety of segmented neutrophils is a warning sign that something is flawed with the body. The causes of those changes are very wide and range from bacterial and viral infections to autoimmune and degenerative processes.
Fever, rapid pulse, rapid respiratory, vomiting and diarrhea are symptoms that indicate a possible infectious process. On the opposite hand, when there may be difficulty respiratory, signs of dehydration and lack of consciousness, seek help as soon as possible.
