The eGFR blood test measures your estimated glomerular filtration rate—a key indicator of how well your kidneys are filtering waste from your blood. Higher eGFR values indicate better kidney function, while lower values may signal declining kidney health.
Your kidneys contain millions of tiny filters called glomeruli that remove waste and excess fluid from your bloodstream. The eGFR blood test estimates how much blood these filters can process per minute, adjusted for your body size. This calculation uses your creatinine level (a waste product from muscle metabolism) along with your age, sex, and race to provide an accurate assessment of kidney function.
