A glomerular filtration rate (GFR) test is a simple blood test that measures the kidneys’ ability to filter waste. A doctor may order a GFR test to gauge kidney health. The kidneys are a pair of ...
Current equations for estimated glomerular filtration rate (eGFR) that use serum creatinine or cystatin C incorporate age, sex, and race to estimate measured GFR. However, race in eGFR equations is a ...
