Tests and diagnosis

By Mayo Clinic Staff

To determine whether you have chronic kidney disease, you may need tests and procedures such as:

  • Blood tests. Kidney function tests look for the level of waste products, such as creatinine and urea, in your blood.
  • Urine tests. Analyzing a sample of your urine may reveal abnormalities that point to chronic kidney failure and help identify the cause of chronic kidney disease.
  • Imaging tests. Your doctor may use ultrasound to assess your kidneys' structure and size. Other imaging tests may be used in some cases.
  • Removing a sample of kidney tissue for testing. Your doctor may recommend a kidney biopsy to remove a sample of kidney tissue. Kidney biopsy is often done with local anesthesia using a long, thin needle that's inserted through your skin and into your kidney. The biopsy sample is sent to a lab for testing to help determine what's causing your kidney problem.
