Exams and Tests

Tests for chronic kidney disease are vital to help find out:

  • Whether kidney disease happened suddenly or has been happening over a long time.
  • What is causing the kidney damage.
  • Which treatment is best to help slow kidney damage.
  • How well treatment is working.
  • When to begin dialysis or have a kidney transplant.

After you are diagnosed with chronic kidney disease, blood and urine tests can help you and your doctor monitor the disease.

Kidney Dialysis

Your kidneys help filter waste, excess fluid, and toxins from your blood. They are also important for blood cell production and bone health. If kidneys don't work properly, harmful substances build up in the body, blood pressure can rise, and too much fluid can collect in the body's tissues, which leads to swelling, called edema. If your kidneys fail, you will need a life-saving treatment called dialysis to take over their job.

Tests to check kidney function

When kidney function is decreased, substances such as urea, creatinine, and certain electrolytes begin to build up in the blood. The following tests measure levels of these substances to show how well your kidneys are working.

Tests for anemia

If the kidneys don't produce enough of the hormone erythropoietin needed to make red blood cells, anemia can develop. The following tests help monitor anemia:

Other tests

Your doctor may use other tests to monitor kidney function or to find out whether another kidney disease or condition is contributing to reduced kidney function.

Early screening for chronic kidney disease

Experts recommend screening tests for chronic kidney disease in high-risk groups, such as people with diabetes or high blood pressure. Kidney disease runs in families, so close family members may also want to have their kidney function tested. Being diagnosed with kidney disease before it has progressed gives you the best chance to control the disease.
