Granulocytes earn their name from a single diagnostic feature: visible granules that appear when the cell is stained with specific dyes. This granule-based classification unites four otherwise distinct cell types — neutrophils, eosinophils, basophils, and mast cells — into one immune cell family. Staining remains the fastest way to identify them in a blood smear.
