Creatinine Levels Explained: What Your Kidney Test Results Mean

Creatinine is a waste product produced during normal muscle metabolism. Healthy kidneys filter creatinine from the blood and remove it through urine. When kidney function declines, creatinine levels in the bloodstream may rise. Understanding creatinine levels is an important part of evaluating kidney health and detecting kidney disease early.

At Tambaram Medical Center, our specialists help patients understand kidney test results and provide advanced care for kidney conditions across Tambaram and Chennai.

Creatinine blood test used to measure kidney function and detect kidney disease.

What Is Creatinine?

Creatinine is a chemical waste product produced from muscle activity. Because the kidneys filter creatinine from the blood, doctors often measure creatinine levels to evaluate kidney function.

Normal Creatinine Levels

• Adult men: 0.7 to 1.3 mg/dL
• Adult women: 0.6 to 1.1 mg/dL

Higher or lower levels may indicate kidney issues or other medical conditions.

Why Creatinine Levels Matter

Creatinine levels are used to estimate the glomerular filtration rate (eGFR), which measures how effectively the kidneys filter waste from the blood.

Causes of High Creatinine Levels

• Chronic kidney disease
• Kidney infections
• Kidney stones
• Severe dehydration
• Certain medications

Kidney stones can affect kidney function and increase creatinine levels. Learn more here: Kidney Stones.

Symptoms of High Creatinine

• Fatigue
• Swelling in feet and ankles
• Reduced urination
• Nausea
• High blood pressure
