HemaBook Chapter 1: The Stories of Platelet Clump

Thrombocytopenia is a condition characterized by abnormally low levels of platelets in the blood.

It is an in vitro phenomenon caused by platelet clumping that results in reporting of a spuriously low platelet count by automatic hematology analyzers.
