Thrombocytopenia, defined as a platelet count of less than 150,000/microL, is clinically suspected when there is a history of easy bruising or bleeding in a child. It may also present as an incidental finding during routine evaluation or during investigations performed for other reasons.

Causes of thrombocytopenia in children will be reviewed here. Causes of neonatal thrombocytopenia, the clinical manifestations and evaluation of thrombocytopenia, evaluation of bleeding symptoms in children, and details of specific causes thrombocytopenia are discussed separately:

(See "Causes of neonatal thrombocytopenia".)

(See "Clinical manifestations and evaluation of thrombocytopenia in children".)

(See "Approach to the child with bleeding symptoms".)
