Accessed July 15, 2020. What does my eGFR mean? Newer eGFR tests that include both creatinine and a protein called cystatin C may be more accurate, according to 2021 research. Healthcare providers measure eGFR in milliliters of cleansed blood per minute per body surface (a measurement that reads mL/min/1.73m2). Scientists use genetic rewiring to increase lifespan of cells, Beyond amyloid and tau: New targets in developing dementia treatments, Napping longer than 30 minutes linked to higher risk of obesity and high blood pressure, Activity 'snacks' could lower blood sugar, complication risk in type 1 diabetes, What to know about kidney disease in African American people. eGFR is a mostly reliable test for doctors to know how well your kidneys are working. Researchers are currently working on alternative formulas that dont rely on creatinine. In search of a better equation performance and equity in estimates of kidney function. Health inequities and the inappropriate use of race in nephrology. GFR measurements can vary by age. A more accurate method to estimate glomerular filtration rate from serum creatinine: a new prediction equation. SCr)-1.154x (age)-0.203x (0.742 if female) x (1.210 if African American) They proposed a new approach to estimating eGFR in September 2021. If you have diabetes, your doctor will check your kidney function yearly by testing and measuring your GFR and urine albumin levels. Last medically reviewed on October 22, 2021. What does my eGFR mean? Normal GFR: >60 mL/Min. For this reason, they recommend using a new 2021 CKD-EPI creatinine equation to calculate eGFR, which excludes ethnicity as a factor. In most healthy people, the normal GFR is 90 mL/min/1.73 m2 or higher. Our website services, content, and products are for informational purposes only. The formulas currently used for eGFR modify results. Published 2010 Oct 4. doi:10.4061/2011/283137. This supports the goal of narrowing some of the disparities in CKD, including the higher prevalence of CKD in African Americans compared to white patients, the higher rate of progression to ESRD, and transplant eligibility. Are there medications for CKD? Black Doctors USA provides a service on its website for finding Black doctors, including kidney specialists, in the local area. This could lead to: One strategy to determine eGFR in a way that isnt influenced by race would be to use a biomarker other than creatinine in the calculation. (2014). If you arent sure, its best to ask your doctor. In the United States, a different version of the formula is generally used when calculating eGFR test results for Black people. GFR stands for glomerular filtration rate.
