Amyloidosis: Diagnosis

Blood and urine tests can reveal the presence of amyloid protein, but tissue or bone-marrow biopsy is necessary to positively diagnose amyloidosis. Once the diagnosis has been confirmed, additional laboratory tests and imaging procedures are performed to determine:

• which type of amyloid protein is involved
• which organ (s) or system (s) have been affected
• how far the disease has progressed
