Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE table_221653_1 ( platelet_count VARCHAR, partial_thromboplastin_time VARCHAR, bleeding_time VARCHAR )

### Question ###
What is the platelet count when partial thromboplastin time and bleeding time are unaffected?

SELECT platelet_count FROM table_221653_1 WHERE partial_thromboplastin_time = "Unaffected" AND bleeding_time = "Unaffected"
