What is eGFR (Creatinine + Cystatin C)?

The estimated glomerular filtration rate (eGFR) using both creatinine and cystatin C is a calculated marker of kidney function.‍ It provides a more accurate estimate of how well your kidneys are filtering waste from the blood compared to using creatinine alone.

What does it assess?

This test assesses kidney function, particularly in early-stage chronic kidney disease (CKD) where creatinine-only eGFR may not be sensitive enough.‍ It’s useful for evaluating kidney health, especially in individuals with muscle mass variations or borderline eGFR values.

How do I optimize my eGFR?

To support kidney function, maintain healthy blood pressure, stay hydrated, limit sodium intake, and manage blood sugar if diabetic.‍ Avoiding nephrotoxic medications or excessive protein intake may also help preserve filtration capacity.

What do high and low eGFR levels mean?

High eGFR is generally normal, though excessively high values may be inaccurate.‍ Low eGFR indicates reduced kidney function, potentially pointing to chronic kidney disease.‍ Early detection allows for lifestyle and medical interventions to slow progression.
