What are the treatments for ITP? Your doctor will choose your treatment based on the total number of platelets you have.
Diagnosis
To diagnose immune thrombocytopenia, your doctor will try to exclude other possible causes of bleeding and a low platelet count, such as an underlying illness or medications you or your child may be taking.
Blood tests can check the levels of platelets. Rarely, adults might need a bone marrow exam to rule out other problems.
