IgA Nephropathy - Berger's Disease

How is the disease diagnosed?

Diagnosis of Berger's disease begins with a medical history and physical exam. A urine test called a urinalysis will show blood, and often protein, in the urine. This often makes the healthcare provider suspect Berger's disease. A blood test can be done to measure the level of IgA antibodies, which is often higher than normal.

A kidney biopsy is usually needed to confirm the diagnosis. This involves inserting a special needle through the skin of the back and into the kidney. A small piece of kidney is removed with the needle. This piece can then be sent to the lab for examination.
