What tests help diagnose a kidney stone?

ANSWER

There are several ways your doctor can test for kidney stones.

Imaging tests can help tell your doctor how big it is and exactly where it’s located:

Blood tests can show whether you have too much of substances in your blood, such as uric acid or calcium, that can cause kidney stones to form.

A urine test can check for kidney stone-forming minerals in your pee or show that you don't have certain substances to help stop them from forming.

  • X-rays
  • CT scans
  • Ultrasound
