What term refers to a low platelet count?

The term that refers to a low platelet count is thrombocytopenia. This condition is characterized by the insufficient production of platelets or increased destruction of platelets in the blood. Platelets, or thrombocytes, are crucial for blood clotting, and a lower than normal count can lead to increased bleeding and bruising.

Understanding the terminology is essential in laboratory medicine, as it helps in diagnosing and managing various hematological disorders. Thrombocytosis, which refers to an elevated platelet count, and leukopenia or leukocytosis, which pertain to low or high white blood cell counts respectively, do not relate to platelet counts and thus do not define the condition in question.
