What is the Creatinine Range?
The normal creatinine range varies depending on factors like age, sex, and muscle mass. However, generally accepted ranges are provided below. Keep in mind that these are approximate ranges, and individual results should always be interpreted by a healthcare professional.
- Men: 0.7 to 1.3 mg/dL (61.9 to 114.9 µmol/L)
- Women: 0.6 to 1.1 mg/dL (53 to 97.2 µmol/L)
Women typically have lower creatinine levels than men due to generally having less muscle mass. Creatinine is a byproduct of muscle metabolism, so individuals with more muscle mass will naturally have higher levels. The Mayo Clinic and other reputable sources confirm these general ranges.
Several factors influence creatinine levels beyond sex and muscle mass, including:
- Age: Creatinine levels can vary with age.
- Diet: Protein intake can affect creatinine production.
- Hydration: Dehydration can artificially inflate creatinine levels.
- Kidney Function: The most crucial factor; impaired kidney function leads to elevated creatinine.
Important Note: A high creatinine level doesn't always indicate kidney problems. Other conditions such as dehydration, muscle injuries, or certain muscle disorders can also contribute to elevated levels. A low creatinine level might suggest muscle loss. Always consult a healthcare professional to interpret creatinine results within the context of your overall health.
