Neutrophils are the most common punch in of white blood cell.
Like all white blood cells, they are involved in fighting infection and healing from injury and disease.
Neutrophils are especially associated with bacterial and fungal infections.

An increase in immature neutrophils in the blood is often a sign of infection.
It can also be because of other issues, including injury, physical stress, and cancer.

Why Are Some Neutrophils Immature?
Neutrophils are formed in thebone marrow.
The majority of the neutrophils in the bone marrow are immature.
These include myeloblasts, promyelocytes, myelocytes, metamyelocytes, and bands.
Mature neutrophils are described as segmented neutrophils because their nuclei have a segmented appearance when examined with a microscope.
This is typically due to an infection and is called a left shift.
What Are the Symptoms and Causes of Immature Neutrophils?
Symptoms include:
Immature neutrophils are associated withsepsis, a severe systemic (whole-body) reaction to an infection.
Sepsis can be life-threatening, and prompt medical attention and treatment are needed.
How Are Immature Neutrophils Diagnosed?
Immature neutrophils can be identified with acomplete blood count (CBC), which is a blood test.
You might have a repeat CBC or need additional tests to identify the cause.
Examples of additional tests can include:
How Do You Treat Immature Neutrophils?
In general, immature neutrophils will reach a normal level after treatment of the underlying cause.
Even though they are immature, it has been shown that these cells are effective in fighting infections.
You might need treatment for the infection and managing symptoms of the infection.
An increase in band neutrophils is usually temporary and indicative of an infection.
Sometimes band neutrophils can increase due to inflammatory diseases or cancer.
Your medical history, symptoms, and blood tests would guide your treatment plan.
Treatment is directed at the underlying problem.
They are a sign that your body is actively making more neutrophils than usual to overcome the infection.
You may even be already recovering from a mild or moderate infection.
The percentage of band neutrophils normally ranges from 0 to 3%.
Band neutrophils are immature neutrophils that have a nucleus with a band-like appearance when examined with a microscope.
Many types of cancer can cause a high neutrophil count.
