Glomerular filtration rate (GFR) is a marker of kidney health. Learn the normal range of eGFR, the purposes of the test, and how to interpret the results.

Glomerular filtration rate (GFR) is the best overall index of kidney function. Normal GFR varies according to age, sex, and body size, and declines with age.

Jun 1, 2023 · When looking at your eGFR results, a higher number is better. In general, an eGFR value lower than 60 is a sign that your kidneys may not be working properly. An eGFR lower than 15 is a marker of kidney failure. In general, there are …

Use this GFR Calculator tool to help you determine which stage of kidney disease you are in currently. What Your GFR Result Means. Completely healthy kidney function is measured at a glomerular filtration rate (GFR) of around 100, which means that …

Nov 19, 2023 · Chronic kidney disease (CKD) is divided into five stages, ranging from stage 1 to stage 5. Each stage is determined by a blood test known as the estimated glomerular filtration rate (eGFR), which establishes how well your kidneys filter waste and …

Jun 17, 2021 · Healthcare providers use estimated glomerular filtration rate (eGFR) to determine if you have kidney disease, and if so, what stage. eGFR measures your kidneys’ ability to filter toxins or waste from your blood. A very low number may indicate kidney failure, which requires dialysis or a kidney transplant.

Nov 9, 2023 · A GFR of 15 or lower is a sign of kidney failure. This is when your kidneys stop being able to effectively filter wastes and extra fluids from your blood.

Jul 13, 2022 · Your kidneys filter your blood by removing waste and extra water to make urine. The glomerular filtration rate (GFR) shows how well the kidneys are filtering. An estimated 37 million adults in the United States may have chronic kidney disease (CKD) but nearly 90% are unaware of their condition.

The GFR (glomerular filtration rate) Calculator estimates GFR values based on factors including serum creatinine value, age, race, and gender. For comparison purposes, the results for three prevalent formulas used for estimating GFR are provided.

Mar 17, 2025 · GFR varies by age, sex, and body size and is used to assess renal health, detect kidney disease, and guide treatment. Let’s explore normal GFR values across different age groups, factors influencing GFR, and clinical implications.
