How well your kidneys work is called kidney function. Your kidneys have the important job of filtering your blood. They remove waste products and extra fluid from your body.
When your kidneys do not work as they should, waste can build up in your blood. This can make you sick. If you have long-term (chronic) kidney disease, you may not have any symptoms until your kidney function is very low.
Blood and urine tests can help show how well your kidneys are working. They can help your doctor know:
Tests that check kidney function may include:
This test measures how well your kidneys are filtering your blood. If your creatinine clearance goes down, this means that your kidneys aren't filtering your blood as well.
Experts recommend screening tests for people who are at higher risk of the disease. This includes people with diabetes or high blood pressure. If you have diabetes, your doctor may recommend yearly testing for protein in your urine. When to begin testing depends on the type of diabetes you have.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if you are having problems. It's also a good idea to keep a list of the medicines you take. Ask your doctor when you can expect to have your test results.
