    How to diagnose Immune Thrombocytopenia ?
    ### Response:
    Your doctor will diagnose immune thrombocytopenia (ITP) based on your medical history, a physical exam, and test results.
                
Your doctor will want to make sure that your low platelet count isn't due to another condition (such as an infection) or medicines you're taking (such as chemotherapy medicines or aspirin).
