Creatinine is a waste product that’s generated when you use your muscles. Eating lots of protein may also produce small amounts of this organic compound.
Your bloodstream transports creatinine to your kidneys, where your body filters it out through your urine. However, if your kidneys aren’t working properly, the level of creatinine in your blood can build up.
Your healthcare provider may check your blood and urine for creatinine, as well as order other tests to evaluate the health of your kidneys. A normal level depends on your age, race, gender, and body size.
Abnormal creatinine levels may be a sign of kidney disease.
You may need a creatinine test if you have these symptoms:
- changes in urination (frequency, pain, foaminess, or blood)
- muscle cramps
- nausea or vomiting

- swelling in the feet or ankles
Your doctor may likewise recommend regular creatinine testing if you have any of the following conditions, which may contribute to decreased kidney function:
- high blood pressure
- thyroid disease
- autoimmune diseases
- bacterial infection of the kidneys
- a blocked urinary tract
- a family history of kidney disease
Creatinine levels can also rise temporarily from strenuous exercise or using certain medications like sulfamethoxazole, trimethoprim, or chemotherapy drugs.
