Table schema:
CREATE TABLE table_221653_1 (platelet_count VARCHAR, prothrombin_time VARCHAR, bleeding_time VARCHAR)

Question: How many time does the platelet count occur when prothrombin time and bleeding time are prolonged?
SQL: SELECT COUNT(platelet_count) FROM table_221653_1 WHERE prothrombin_time = "Prolonged" AND bleeding_time = "Prolonged"
