Understanding Creatinine (CRE)

Creatinine (CRE) is a key biomarker in blood tests that a marker of kidney function, indicating how well the kidneys filter waste.

What is Creatinine?

A marker of kidney function, indicating how well the kidneys filter waste.

Normal Range

Low < 0.6 mg/dL
Normal 0.6 - 1.3 mg/dL
High > 1.3 mg/dL

The normal Creatinine range is between 0.6 and 1.3 mg/dL.

High Creatinine Levels (Above 1.3 mg/dL)

Causes of High Creatinine

High creatinine suggests kidney dysfunction, dehydration, or excessive protein intake. Improving hydration, moderating protein intake, and optimizing kidney health can help lower levels.

Health Effects of High Creatinine

Elevated creatinine suggests kidney impairment, leading to toxin buildup in the blood, increased blood pressure, and kidney failure.

Low Creatinine Levels (Below 0.6 mg/dL)

Causes of Low Creatinine

Low creatinine may indicate muscle wasting, malnutrition, or liver disease. A protein-rich diet and resistance training can help maintain healthy muscle mass and creatinine levels.

Health Effects of Low Creatinine

Chronically low creatinine may signal declining muscle mass, reduced metabolic function, and poor endurance.

Treatment and Management

For High Creatinine

  • Medical evaluation to determine the underlying cause
  • Lifestyle modifications as recommended by your healthcare provider
  • Regular monitoring of Creatinine levels
  • Follow-up testing as needed

For Low Creatinine

  • Medical evaluation to identify the root cause
  • Appropriate supplementation if recommended
  • Dietary changes as advised
  • Regular monitoring and follow-up

When to See a Doctor

Consult your healthcare provider if:

  • Your Creatinine levels are consistently outside the normal range
  • You experience symptoms associated with abnormal Creatinine levels
  • You have risk factors for conditions affecting Creatinine levels
  • You’re taking medications that may affect Creatinine levels

Prevention

  • Regular health check-ups
  • Balanced diet
  • Regular exercise
  • Stress management
  • Adequate sleep
  • Avoiding known triggers
