Neutrophils are vital white blood cells that protect the body by fighting infections and healing damaged tissues.
They play a crucial role in diagnosing and monitoring health conditions. Their levels indicate immune system activity and potential underlying issues.
Neutrophils are a type of white blood cell and the most prominent component of your immune system.
These cells act as the body's first line of defense against infections by attacking bacteria, viruses, and fungi.
Neutrophils travel quickly to infection sites and release enzymes to destroy harmful microorganisms, playing a vital role in the immune response.
In medical diagnostics, neutrophils are measured to assess the body's ability to combat infections. The ANC, or absolute neutrophil count, represents the number of neutrophils present in your blood. It is important for identifying immune system health and diagnosing conditions like infections, inflammation, and some blood disorders.

Testing for neutrophils is essential in many medical situations to evaluate immune system health. Below are common scenarios where neutrophil testing may be recommended:
Neutrophil levels are measured using a blood test. Typically, this test is part of a complete blood count (CBC), which provides detailed information about various blood components. The ANC, or absolute neutrophil count, is calculated by multiplying the total white blood cell count by the percentage of neutrophils and band cells.
Note: The units of measurement and normal ranges may vary depending on the laboratory and specific testing methods used

High neutrophil levels, or neutrophilia, can occur due to various reasons. This condition indicates an active immune response or inflammation in the body. Common causes include:
Low neutrophil levels, or neutropenia, suggest a weakened immune system. This can make you more susceptible to infections. Common causes include:
If you suspect abnormal neutrophil levels or experience related symptoms, consult a general practitioner. They can assess your condition and, if necessary, refer you to a hematologist or immunologist for further evaluation and treatment.
Segmented neutrophils are mature neutrophils that play a critical role in fighting infections. They are distinguished by their segmented nucleus, which allows them to move efficiently through blood vessel walls to reach infection sites.
High neutrophils during pregnancy are caused by hormonal changes that boost the immune system to protect both the mother and the baby. This increase helps the body adapt to potential infections and maintain a healthy pregnancy environment.
Hypersegmented neutrophils are white blood cells with nuclei that have more segments than usual. They are often associated with conditions like vitamin B12 or folate deficiencies.
A combination of low lymphocytes and high neutrophils can sometimes signal the presence of cancer or other serious conditions. This imbalance may occur due to the body’s response to tumors or as a result of treatments like chemotherapy.
