Why it's doneBy Mayo Clinic staff
A serum creatinine test — which measures the level of creatinine in your blood — can indicate whether your kidneys are working properly. How often you need creatinine tests depends on any underlying conditions and your risk of kidney damage. For example:
- If you have type 1 or type 2 diabetes, your doctor may recommend a creatinine test at least once a year.
- If you have kidney disease, your doctor may recommend creatinine tests at regular intervals to monitor your condition.
- If you have an illness that may affect your kidneys — such as high blood pressure or diabetes — or you're taking medication that may affect your kidneys, your doctor may recommend creatinine tests.
