    Signs and tests

    IgA nephropathy usually is discovered after one or more episodes of dark or bloody urine in a person with no other symptoms of kidney disorder.

    There are no specific changes seen during a physical examination. Occasionally, blood pressure may be high or swelling of the body may be present.

    Tests include:

    • Creatinine and blood urea nitrogen (BUN) to measure kidney function
    • Urinalysis will show blood and protein in the urine
    • Kidney biopsy confirms the diagnosis
    • Urine immunoelectrophoresis
