Idiopathic Thrombocytopenic Purpura

Diagnosis

Experienced hematologists at Mayo Clinic begin with a thorough history and physical examination.

Diagnostic Tests

Mayo Clinic physicians may use a variety of tests to diagnose idiopathic thrombocytopenic purpura.

Blood Tests

Complete blood counts determine the number of red blood cells, white blood cells, and platelets within the blood. Results from this and other blood tests can provide important clues to a patient's condition. The hematopathology laboratories at Mayo Clinic offer sophistocated tests and specialized expertise to help hematologists properly diagnose each patient's condition. Physicians around the world send blood samples to Mayo's laboratories for their expertise.

Bone Marrow Biopsy

Experienced teams conduct bone marrow biopsies, inserting a needle into a bone in the back of the pelvis to gather a sample of bone marrow for examination. Bone marrow biopsy is a relatively minor procedure that can be performed as an outpatient with a local anesthetic (numbing medication) with or without light sedation to minimize any pain and discomfort.
