Understanding Serum Creatinine
Serum Creatinine is a key indicator of kidney function. Creatinine is a waste product formed naturally in the body during the breakdown of muscle tissue. The kidneys filter it out from the blood and excrete it through urine. Therefore, measuring creatinine levels in the blood helps evaluate how efficiently the kidneys are functioning and detect any possible kidney disorders early.
Doctors at Curis Life Clinic may recommend a Serum Creatinine test if you experience symptoms that suggest kidney dysfunction, such as:
- Changes in urination patterns
- Swelling in the feet or ankles
- Loss of appetite
- Persistent fatigue or weakness
This test is also advised for individuals at higher risk of kidney problems, including those with:
- Diabetes
- Obesity
- High blood pressure
- Heart disorders
- A family history of kidney disease
The Serum Creatinine test also helps monitor:
- The response to treatment in people already diagnosed with kidney disease
- The effect of certain medications that can impact kidney health
- Kidney function before surgery or certain medical procedures
No special preparation is required for this test — you can eat and drink as usual. However, it’s important to inform your doctor about all medications or supplements you’re taking, as they can influence the test results.
Test result ranges may slightly differ between laboratories based on methods used. Always consult your doctor to interpret your results accurately. The findings help determine kidney function, guide necessary lifestyle changes, and decide whether medication or further evaluation is required.
What Does Serum Creatinine Measure?
The Serum Creatinine Test measures the amount of creatinine present in the blood — a byproduct of muscle metabolism. Since the kidneys are responsible for filtering creatinine, this test provides a reliable picture of kidney efficiency.
- High creatinine levels may indicate reduced kidney function or damage.
- Low creatinine levels can sometimes reflect low muscle mass or malnutrition.
This test helps your doctor at Curis Life Clinic assess overall kidney performance, detect early signs of kidney disease, and ensure timely intervention to maintain your health.
