The chief tools used to diagnose chronic kidney disease (CKD) are:
- Abdominal ultrasound -- This test uses sound waves to take pictures of your internal organs, including your kidneys.
- Computerized tomography (CT) -- A quick and painless exam that takes pictures of the organs or structures in your body.
- Kidney biopsy -- Your doctor will take a tiny amount of tissue from your kidney so that the cause of your disease can be determined.
- Magnetic resonance imaging (MRI) -- This test is used to evaluate body tissue. It can be used to assess injury, or disease, in tissues, nerves, muscles, ligaments, and blood vessels.
Laboratory tests include:
- Blood urea nitrogen (BUN) -- This test tells your doctor how well your kidneys are working by measuring how much nitrogen is in your blood.
- Creatinine -- Your doctor will test your glomerular filtration rate (GFR) to determine the stage of your disease and the amount of kidney function you have.
