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 …

Mar 18, 2025 · An eGFR number between 45 and 59 means your kidneys may have mild to moderate damage and do not work as well as they should to filter waste from your blood. Your eGFR result is XX mL/min/1.73. An eGFR number between 30 and 44 means you may have moderate to severe kidney damage.

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.

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.

CKD is evaluated using two simple tests – a blood test known as the estimated glomerular filtration rate (eGFR) and a urine test known as the urine albumin-creatinine ratio (uACR). Both tests are needed to have a clear picture of your kidney health.

Jul 6, 2023 · Stage 3a CKD means you have mild to moderate loss of kidney function. People with stage 3a CKD have an estimated glomerular filtration rate (eGFR) between 45 and 59 for 3 months or more (confirmed with repeat testing to make sure you don’t have acute kidney injury).

Jan 14, 2019 · Your GFR number tells you how much kidney function you have; as kidney disease worsens, the GFR number decreases. "Normal" GFR is approximately 100, but you will often see it reported as >90 (greater than 90) or >60 (greater than 60).

Mar 12, 2024 · The glomerular filtration rate (GFR) is a measure of how well your kidneys are removing waste from your blood, which can be determined using an estimated GFR (eGFR) test.

Sep 25, 2023 · Stage 3 of chronic kidney disease (CKD) occurs when your estimated glomerular filtration rate (eGFR) falls between 30-59, indicating moderate kidney damage and noticeable loss of kidney function. This stage is separated into 2 sub-stages: stage 3a kidney disease with an eGFR of 45-59 and stage 3b with an eGFR of 30-44.

Completely healthy kidney function is measured at a glomerular filtration rate (GFR) of around 100, which means that the kidneys are working at 100 percent. Your kidney function is still considered normal if the GFR number is 90 or greater. If your GFR is 45, you know that your kidneys are working at approximately 45 percent of the normal rate.
