An estimated glomerular filtration rate (eGFR) of 55 milliliters per minute per 1.73 meters squared may be an early sign of chronic kidney disease (CKD). What is the NKF doing to address concerns about using race in measuring eGFR? The eGFR calculation accounts for biological factors like age, sex, and body weight. NKFs educational offerings include the impact of kidney disease ondiverse communities, and the reasons why communities of color have been disproportionately affected by COVID-19. I recommend that you have urine testing as well for blood, protein and infection. The glomerular filtration rate, or GFR, is a measure of how well your kidneys are cleaning your blood, which can be determined using an estimated GFR test (eGFR). As kidney disease gets worse, the GFR number goes down. NKF is working to help identify, confront and reverse them, Confirming that kidney function is normal for a potential living kidney donor, Making sure the right dose of medicine is used, Enrollment in clinical trials that use kidney function as an inclusion or exclusion criterion, Making sure the right type of imaging tests and dyes are used, When to refer someone to a nephrologist or kidney doctor, When to start an evaluation for a kidney transplant.

The kidney consists of tiny filters called glomeruli that remove waste material from the blood. Kidneys filter (remove) almost all of the creatinine from the blood. In: Yu ASL, Chertow GM, Luyckx VA, Marsden PA, Skorecki K, Taal MW, eds. This makes it impractical for both clinicians and patients.

The lab doesnt know your ethnicity or race, so the report includes both numbers. Your kidneys have tiny filters called glomeruli.
