Is a higher percent of neutrophils an infection?

Neutrophils are a type of white blood cell that helps the body fight infection. When the body is fighting an infection, the number of neutrophils in the blood increases. This is called neutrophilia.

Neutrophilia can be caused by a variety of conditions, including:

* Bacterial infections, such as pneumonia and sepsis

* Viral infections, such as the flu and chickenpox

* Fungal infections, such as Candida and Aspergillus

* Parasitic infections, such as malaria and toxoplasmosis

* Inflammatory diseases, such as rheumatoid arthritis and Crohn's disease

* Certain types of cancer, such as leukemia and lymphoma

* Burns

* Trauma

* Surgery

In most cases, neutrophilia is a sign that the body is fighting an infection. However, it is important to note that neutrophilia can also be caused by other conditions, so it is important to see a doctor if you have neutrophilia to determine the cause.

The percentage of neutrophils in the blood is reported as the absolute neutrophil count (ANC). The ANC is calculated by multiplying the total white blood cell count by the percentage of neutrophils.

The normal ANC range is 1,500 to 7,000 cells/μL. An ANC below 1,500 cells/μL is called neutropenia, while an ANC above 7,000 cells/μL is called neutrophilia.

Neutrophilia is usually treated by treating the underlying condition that is causing it. In some cases, neutrophilia may be treated with medications that reduce the number of neutrophils in the blood.
