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_1555308_1 ( bleeding_time VARCHAR, prothrombin_time VARCHAR, platelet_count VARCHAR )

### Question ###
What are all the possible bleeding time results where prothrombin time and platelet count are both unaffected?

### Accurate SQL ###

SELECT bleeding_time FROM table_1555308_1 WHERE prothrombin_time = "Unaffected" AND platelet_count = "Unaffected"
