neutrofiilimääränä

Neutrofiilimääränä refers to the absolute count of neutrophils in a person's blood. Neutrophils are a type of white blood cell, also known as granulocytes, that play a crucial role in the immune system's response to bacterial and fungal infections. They are the most abundant type of white blood cell and are often the first responders to sites of inflammation.

The normal range for absolute neutrophil count (ANC) can vary slightly depending on the laboratory, but generally falls between 1.5 to 8.0 x 10^9 cells per liter. A low neutrophil count, known as neutropenia, can significantly increase the risk of infection. This can be caused by various factors, including certain medications (especially chemotherapy), viral infections, autoimmune disorders, and bone marrow problems. Conversely, a high neutrophil count, called neutrophilia or neutrocytosis, is often a sign of infection or inflammation. It can also be seen in response to stress, certain cancers, and after strenuous exercise.

Measuring the absolute neutrophil count is a common component of a complete blood count (CBC) test. Doctors use this information to help diagnose and monitor a variety of medical conditions, particularly those involving the immune system or potential for infection.
