The Serum Creatinine Test is a blood test used to measure the level of creatinine, a waste product generated by muscle metabolism. It is primarily used to assess kidney function, as creatinine is filtered by the kidneys. Elevated levels may indicate impaired kidney function or kidney disease.
Indications for Serum Creatinine Test:
● Chronic kidney disease (CKD): To evaluate kidney function in individuals with diabetes, hypertension, or a family history of kidney disease.
● Acute kidney injury (AKI): In cases of sudden kidney dysfunction due to infection, medications, or dehydration.
● Monitoring kidney function: To track kidney function in individuals on dialysis or undergoing chemotherapy.
● Pre-surgical assessment: To assess kidney function before surgeries, especially in patients with underlying kidney conditions.
How Serum Creatinine Test Works:
● A blood sample is drawn from a vein in the arm and analyzed for the level of creatinine. The result is typically measured in milligrams per deciliter (mg/dL).
Normal Range:
●Normal serum creatinine levels:
● Men: 0.6–1.2 mg/dL
● Women: 0.5–1.1 mg/dL
● Children: 0.2–0.7 mg/dL
Abnormal Test Significance:
● Elevated creatinine levels: High levels may indicate impaired kidney function, dehydration, renal failure, or glomerulonephritis.
● Low creatinine levels: May suggest muscle wasting or malnutrition, but is less commonly seen in kidney disease.
Management Based on Results:
● For elevated creatinine: Treatment focuses on controlling blood pressure, managing diabetes, or initiating dialysis if kidney function is severely impaired.
● For low creatinine levels: Investigate possible causes, such as muscle atrophy or nutritional deficiencies, and provide appropriate nutritional support.
Price in India:
Approx. ₹200 – ₹500 for a serum creatinine test.
Frequently Asked Questions
What causes creatinine levels to rise?
Kidney dysfunction, dehydration, or conditions like glomerulonephritis or diabetic nephropathy can lead to high creatinine levels.
Can serum creatinine levels be normal with kidney disease?
Yes, creatinine levels may remain normal in the early stages of kidney disease, which is why other tests, like glomerular filtration rate (GFR), may be used for diagnosis.
Disclaimer: Serum creatinine is a key indicator of kidney function but should be interpreted alongside other tests such as GFR and clinical symptoms.
