Definition
Noun: A medical condition characterized by an abnormally low level of all three major types of blood cells: red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes). This deficiency is typically associated with serious underlying issues affecting bone marrow function.

Antonyms
