Bandneutrofiileinä

Bandneutrofiileinä is a Finnish term referring to a specific type of white blood cell. Neutrophils are a crucial component of the innate immune system, responsible for phagocytosing (engulfing and destroying) bacteria and fungi. The term "band" refers to the immature or unsegmented form of the neutrophil. Normally, mature neutrophils have a segmented nucleus, appearing as multiple lobes. Band neutrophils, on the other hand, have a nucleus that is not yet fully segmented, often appearing as a horseshoe or sausage shape.

An increase in the number of band neutrophils in the blood, known as a "left shift," typically indicates that the body is responding to an infection or inflammatory process. This occurs when the bone marrow rapidly releases immature neutrophils into circulation to combat the threat. While a moderate increase can be a normal response, a significant or persistent left shift may warrant further medical investigation to identify the underlying cause. The presence and count of band neutrophils are often assessed as part of a complete blood count (CBC) test.
