Which blood component has a normal range of 300-500 x 10^6/L?

The blood component that typically has a normal range of 300-500 x 10^6/L is monocytes. Monocytes are a type of white blood cell and play a crucial role in the immune response by helping to fight off infections and by removing dead or damaged cells.

In contrast, other types of white blood cells, such as lymphocytes, eosinophils, and basophils, have different normal ranges. Lymphocytes, for instance, usually vary between approximately 1,000 and 4,800 cells per microliter, which translates to a higher count than the specified range. Eosinophils generally range between 0-500 cells per microliter, reflecting a significantly lower range, while basophils are usually even lower, typically around 0-100 cells per microliter. Understanding these normal ranges is essential for interpreting blood tests and assessing an individual's immune status.
