Creatinine Test

The Creatinine test measures the level of creatinine in the blood. Creatinine is a waste product that is produced by muscle metabolism, and it is normally removed from the body by the kidneys. The creatinine test is used to evaluate kidney function and to detect and monitor kidney disease.

Pre-test preparation: There is no specific preparation required for a Creatinine test.

Testing method: The Creatinine test is a blood test. A healthcare provider will take a sample of blood from the patient’s arm, usually from a vein in the elbow or the back of the hand. The blood sample will be sent to a laboratory for analysis.

Symptoms for prescribing this test: The Creatinine test may be ordered if a person has symptoms of kidney disease such as fatigue, weakness, decreased urine output, or swelling in the legs and ankles, or if a healthcare provider suspects an underlying condition that may affect kidney function.

Diagnosis: Creatinine test results can be used, along with other tests such as a urinalysis and a creatinine clearance test, to diagnose and monitor kidney disease, and to evaluate the effectiveness of treatment.

Reference range and normal values: The normal range for creatinine levels in the blood varies depending on the laboratory that performs the test, but it typically ranges between 0.5-1.3 mg/dL for men and 0.4-1.2 mg/dL for women.
