Glomerular Filtration Rate (GFR)

Glomerular Filtration Rate (GFR) measures how well your kidneys are filtering blood and removing waste. It indicates the amount of blood passing through tiny filters called glomeruli in your kidneys each minute. A normal GFR suggests healthy kidney function, while a low GFR may signal kidney problems or disease. Doctors often estimate GFR using blood tests that analyze substances like creatinine. Monitoring GFR helps assess kidney health, diagnose issues early, and guide treatment to prevent further damage.
