Here's why:
* Neutrophils are phagocytes: They engulf and destroy bacteria, essentially eating them up.
* Elevated neutrophil count: When a bacterial infection is present, your body produces more neutrophils to fight it off. This leads to a high neutrophil count, also known as neutrophilia, in your blood.
While other white blood cells like lymphocytes and monocytes are also involved in fighting infections, a high neutrophil count is particularly suggestive of a bacterial infection.
Important Note: A high neutrophil count doesn't always mean you have a bacterial infection. It can also be caused by other things like inflammation, stress, and certain medications. It's important to have a doctor diagnose the cause.
