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

Question: What is the result for partial thromboplastin time when prothrombin time and bleeding time are prolonged?
SQL: SELECT partial_thromboplastin_time FROM table_221653_1 WHERE prothrombin_time = "Prolonged" AND bleeding_time = "Prolonged"
