estimated glomerular filtration rate

Estimated Glomerular Filtration Rate (eGFR) is a blood test that measures how well your kidneys are filtering waste and excess fluids from your blood. It’s calculated using your blood creatinine level, age, sex, and sometimes race. A higher eGFR indicates better kidney function, while a lower value may suggest impaired kidney health. eGFR helps doctors detect early signs of kidney disease, monitor its progression, and guide treatment decisions. It’s a useful, non-invasive way to assess kidney performance and overall health related to kidney function.
