Glomerunephritis: Tests and Diagnosis

What tests are used to diagnose glomerulonephritis?

Blood and urine tests are commonly used to diagnose glomerulonephritis or IgA nephropathy. The most important blood test is the one that checks for normal kidney function. It is called creatinine and helps the doctor determine if the disease is mild or severe. A test called C3 complement is also obtained to help separate acute glomerulonephritis from IgA nephropathy.
