Basophils are cells that become mast cells and participate in allergic reactions. What is their typical concentration range?

Basophils are a rare type of circulating white blood cell that participate in allergic reactions by releasing histamine and other mediators. They share a relationship with tissue mast cells, and in the bloodstream their numbers are very small compared with other leukocytes. The statement that best fits them describes them as cells related to mast cells and places their normal absolute count in a low range, about 0.0 to 0.2 x 10^9/L. This reflects their rarity in blood while capturing their connection to mast cells. In comparison, neutrophils are far more abundant (typically 2 to 7 x 10^9/L) and lymphocytes usually fall around 1 to 4 x 10^9/L, so the other options describe different cell types or use mismatched ranges.
