What is the Serum Creatinine Test?
The serum creatinine test measures the level of creatinine — a waste product — in your blood. Creatinine is produced by normal muscle activity and is filtered out of the blood by the kidneys. When the kidneys are not working properly, creatinine builds up in the blood. This test is one of the most important indicators of kidney health.
Why is the Serum Creatinine Test Done?
- To check kidney function and diagnose chronic kidney disease (CKD)
- To monitor patients with diabetes or high blood pressure, who are at risk of kidney damage
- To detect acute kidney injury, such as after surgery or severe illness
- To monitor patients taking medications that can affect the kidneys (e.g. NSAIDs, certain antibiotics)
- Routine part of a kidney function panel or metabolic panel
Normal Serum Creatinine Levels
| Group | Normal Range (mg/dL) | Normal Range (µmol/L) |
|---|---|---|
| Adult men | 0.74 – 1.35 mg/dL | 65 – 119 µmol/L |
| Adult women | 0.59 – 1.04 mg/dL | 52 – 92 µmol/L |
| Children | 0.2 – 1.0 mg/dL (varies by age) | 18 – 88 µmol/L |
Ranges are based on MedlinePlus reference values. Men naturally have slightly higher creatinine due to greater muscle mass. A high result usually means the kidneys are not filtering waste effectively.
How to Prepare for the Serum Creatinine Test
- Fasting is not strictly required, but your doctor may ask you to fast if it is part of a broader panel
- Avoid eating large amounts of red meat for 24 hours before the test, as this can raise creatinine levels temporarily
- Inform your doctor about any medications or supplements you take
- A blood sample is collected from a vein in your arm
