The estimated glomerular filtration rate (eGFR) is a test that measures your level of kidney function and determines your stage of kidney disease. Your healthcare team can calculate it from the results of your blood creatinine test, your age, body size, and gender. If your eGFR number is low, your kidneys may not be working as well as they.

Having an accurate eGFR result is essential for managing kidney disease (KD). Important decisions like diagnosing KD, determining drug dosing, when to see a kidney doctor, find out eligibility for a kidney transplant, and when to start dialysis involve eGFR test results. Over the past year and a half, we've been leading the effort to develop race-free eGFR (estimated glomerular filtration.

Estimated glomerular filtration rate (eGFR) calculated using either the MDRD Study equation or the CKD-EPI equation is an estimate of GFR, not the actual GFR. Both equations were derived from large population studies and will generate an estimate of the mean GFR in a population of patients with the same age, gender, race, and serum creatinine.

A normal eGFR is greater than 90, but values as low as 60 are considered normal if there is no other evidence of kidney disease. eGFR is often shown as a percentage of normal because people find it useful to think of kidney function as a percentage, going from 100% (fully functioning) to 0% (no function). Cystatin C - is a new test, not yet.

The CKD Epidemiology Collaboration (CKD-EPI) is a research group with interests in measurement and estimation of GFR (CKD-EPI GFR) and evaluation of surrogate endpoints for clinical trials in CKD (CKD-EPI CT). CKD-EPI was founded by Dr. Andrew S. Levey who served as Director from 2004 to 2018 and continues to serve as co-director.

The CKD-EPI (Chronic Kidney Disease Epidemiology Collaboration) equation was developed in an effort to create a more precise formula to estimate glomerular filtrate rate (GFR) from serum creatinine and other readily available clinical parameters, especially at when actual GFR is >60 mL/min per 1.73m 2.. Researchers pooled data from multiple studies to develop and validate this new equation.

Your eGFR is an estimated number based on a blood test and your age, sex, and body type. eGFR is considered a mostly reliable test for doctors to know how well your kidneys are working. However, the eGFR may not be accurate if you are younger than 18, pregnant, very overweight or very muscular. In addition, other tests such as an ultrasound or.

Values for eGFR vary depending on age, sex and other factors. The rate naturally declines as you age and lose muscle mass. The average eGFR for someone in their 20s is about 116 mL/min/1.73m2. It drops to 85 mL/min/1.73m2 for people in their 60s. An eGFR higher than 60 means you have at least 60% kidney function.

About estimated glomerular rate (eGFR) 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.

An estimated glomerular filtration rate (eGFR) test is a blood test that's used to figure out how well your kidneys are doing their job. The test measures the amount of creatinine in your blood and, using a formula, mathematically derives a number that estimates how well your kidneys are functioning. The formula uses your creatinine levels, age, sex, weight, and race to arrive at that number.
