Question: How often does platelet count occur when prothrombin time and bleeding time are prolonged?

Question: What is the result of a partial thromboplastin time when the prothrombin time and bleeding time are prolonged?

Question: What is the platelet count if the partial thromboplastin time and bleeding time are unaffected?
