What is the normal range for basophils in the blood?

The normal range for basophils in the blood is typically between 0.5% and 1%. Basophils are a type of white blood cell that play a crucial role in the body's immune response, particularly in allergic reactions and inflammation. They are part of the body's defense system and contain histamine, which helps to mediate inflammatory responses.

When interpreting laboratory results, it is essential to understand the significance of each type of white blood cell. Basophils generally constitute a small percentage of the total white blood cell count, which is why their normal range is relatively low compared to other leukocytes.

Responding to elevated basophil levels can indicate various conditions, including allergic reactions, certain types of leukemia, and other myeloproliferative disorders, while a very low count may suggest bone marrow issues or the presence of overwhelming infections which deplete these cells. Understanding the normal range helps in diagnosing and monitoring these conditions effectively.
