Giant Platelets: Morphology and Analyzer Errors

Learn about the morphology of giant platelets in blood smears and the causes of errors during impedance cell counting on hematology analyzers.

Blood smear: giant platelet, exceeding the size of surrounding red blood cells

🔍Giant platelet. 😯Its diameter even exceeds that of a red blood cell. 📌An abundance of such platelet forms can lead to incorrect counting by hematology analyzers that use only the impedance method.
