Why This Biomarker Matters
GFR is the best measure of kidney function. Declining GFR indicates kidney disease progression and guides treatment to prevent kidney failure and reduce cardiovascular risk.
Overview
GFR measures how efficiently your kidneys filter waste from blood, expressed as milliliters of filtrate per minute. It's calculated using creatinine levels adjusted for age, sex, and body size. GFR is the most accurate indicator of kidney function, with different stages indicating mild, moderate, or severe kidney disease. Even small declines in GFR can signal progressive kidney disease requiring monitoring and lifestyle modifications to slow progression.
