Physiological Reference Ranges
The ranges below represent standard adult physiological values. Your laboratory's printed reference range always takes precedence.

What does a low result mean?
A low or mid-range value provides clear confirmation of robust, high-efficiency kidney filtration.
What does a high result mean?
A slightly elevated number suggests calculating the combined creatinine-cystatin C eGFR equation for high precision.
Questions ready for your doctor
Bring these questions to your next consultation to discuss with your healthcare practitioner:
- Does this clarify my kidney health without the bias of athletic muscle mass?
- What is my combined creatinine-cystatin C eGFR rate?
- Is routine yearly monitoring appropriate?
