Some institutions have already stopped using race in the calculation of eGFR. A task force led by the National Kidney Foundation (NKF) and the American Society of Nephrology (ASN) was formed in 2020 to look into the use of race in the GFR test. For African-American patients, this may cause anxiety or concern over what an apparent new abnormal lab value. Two tests are used to check for kidney disease. Kidneys that are functioning well filter creatinine from the blood and into the urine, where its eventually expelled from the body. GFR is a measure of how well your kidneys filter blood. This is an extra number value of about 1.2, called a coefficient. nonsteroidal anti-inflammatory drugs (NSAIDs), Association of Diabetes Care and Education Specialists, National Institute of Diabetes and Digestive and Kidney Diseases, Centers for Disease Control and Prevention, kidney.org/atoz/content/can-my-gfr-get-better, kidney.org/sites/default/files/11-10-0209_diabetes.pdf, niddk.nih.gov/health-information/diabetes/overview/preventing-problems/diabetic-kidney-disease, ncbi.nlm.nih.gov/labs/pmc/articles/PMC7711563/, aacc.org/science-and-research/scientific-shorts/2021/is-a-black-race-coefficient-necessary-for-accurate-evaluation-of-egfr-using-creatinin, diabetes.org/diabetes/complications/kidney-disease-nephropathy, kidneyresearchuk.org/kidney-health-information/living-with-kidney-disease/how-can-i-help-myself/understanding-test-results/, journals.plos.org/plosone/article?id=10.1371/journal.pone.0081835, 10 Foods to Avoid with Kidney Disease and Diabetes, How to Screen for Diabetes-Related Nephropathy.

It focuses on African American people, the scores they may receive, and why. What is GFR African American normal range? the Modification of Diet in Renal Disease (MDRD) formula, developed in 1999, the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formula, developed in 2009, race, specifically whether or not you are Black, a family history of kidney disease or associated conditions, implies that race is a biological construct, when its actually a social construct, automatically applies an across-the-board adjustment that doesnt account for the great amount of diversity thats found within the Black community, places people who identify as multiracial into a single racial category thats not reflective of their identity, inability to take some medications that are hard on the kidneys, such as some. When eGFR is very low, generally under 15 mL/min/1.73m2, it can signify kidney failure or serious disease. What is GFR? Is a Black race coefficient necessary for accurate evaluation of eGFR using creatinine? Should I worry if my GFR is 84? The coefficient for this equation is slightly lower than the one used for the MDRD equation. In search of a better equation performance and equity in estimates of kidney function. Eneanya ND, et al. African-American race has a hazard ratio of 1.196 in the KDRI calculation (approximately 20% increased risk of graft failure). Today, two of the most commonly used ones are: To determine eGFR, both of these formulas incorporate a variety of factors, including your: So, why exactly is race used to help determine eGFR? We include products we think are useful for our readers. Weis L, et al. Until September 2021, the two most common equations for estimating eGFR were the Modification of Diet in Renal Disease (MDRD) equation and the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation.

When GFR is <60 for three months or more, chronic kidney disease (CKD) is present. Its possible that your doctor will ask you to fast for a specific period of time before your blood test, especially if youre having additional tests that require fasting. GFR African American (GFR AA) and GFR NON-African American (GFR NON AA). Our experts continually monitor the health and wellness space, and we update our articles when new information becomes available. Including race in the calculation of eGFR can also have serious potential health effects for Black people. Moderately decreased GFR: 30-59 mL/Min. You have two kidneys. (2021). Makris K, Spanou L. Acute Kidney Injury: Diagnostic Approaches and Controversies. The answer to this question involves research observations that are now decades old. A glomerular filtration rate (GFR) test measures how well your kidneys are carrying out their filtration function. (2020). Estimated glomerular filtration rate (eGFR).

Patient advocate Curtis Warfield describes his care journey with chronic kidney disease (CKD) from diagnosis to transplant. (n.d.). An eGFR test is interpreted to determine if you may have reduced kidney function or kidney disease. (2008). As mentioned above, eGFR is calculated using a formula. However, races other than black or white represented a very small proportion of the study (6%), and the external validation group was less diverse (10% black, 87% white).7. Your age, sex, and body weight can affect your muscle mass and the level of creatine in your blood. An eGFR level below 60 mL/min/1.73m2 for three months is considered an indication of chronic kidney disease. There is no change to the normal reference range. This estimate of kidney function can help doctors diagnose and treat kidney disease. Regularly screening your kidney health is a part of actively managing diabetes. Comparison of equations for estimating glomerular filtration rate in screening for chronic kidney disease in asymptomatic black Africans: A cross sectional study. BMC Nephrology 2017;18(1): 369. 1.

The formulas currently used for eGFR modify results based on whether or not you are Black. (2021). Diao JA, et al. The inclusion of race in the eGFR calculation doesn't consider the ancestral diversity among Black people or individuals who self-identify as being of mixed racial background. Starting on May 4, 2021, UC Davis Health will calculate estimated glomerular filtration (eGFR) rate without a parameter for race. A GFR number of 60 or higher is still considered to be within the normal range. Here are 11 foods to avoid with kidney disease and diabetes. Your kidneys work to filter waste products and excess fluids from your blood, which are then released from your body as urine. In the United States, a different version of the formula is generally used when calculating eGFR test results for Black people. It tells doctors how much blood passes through tiny filters in the kidneys each minute. GFR measurements can vary by age. The group aims to ensure that people in these communities have access to doctors who understand these biases. United States Renal Data System*. For most adults, a GFR of over 90 is considered normal. A kidney transplant is a treatment - not a cure. EIN: 23-7124261. A GFR below 60 may mean kidney disease. Newer eGFR tests that include both creatinine and a protein called cystatin C may be more accurate, according to 2021 research. It may also be used to monitor the status of the kidneys. The NKF-ASN Task Force asked patients, the community and kidney disease experts, including AKF's Medical Advisory Committee, to give advice on how to reduce bias in the equations that estimate how well kidneys work. Treating kidney disease may also help prevent heart disease. The lab report shows two eGFR calculations, one estimate for Black/African Americans and another for non-Black/African Americans. Will I ever need dialysis? 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. However, updated equations now exclude race and ethnicity when calculating eGFR. Glomerular hyperfiltration can happen in the early stages of diabetes. Levey A, Stevens L, Schmid C et al. The blood sample is then sent to a laboratory for testing. Kidney disease can be treated.

This test can be used to diagnose a kidney condition or see if a treatment is working. Over of patients receiving kidney dialysis in this country are African American. Data from the USRDS annual report8 and several recent studies9-10 show that black Americans have a higher prevalence of risk factors for CKD, such as hypertension, diabetes, and abnormal adjunct laboratory markers for renal disease despite a lower prevalence of CKD (eGFR < 60 mL/min) in this population as currently calculated. 2023 American Kidney Fund, Inc. All rights reserved. Race differences in prevalence of chronic kidney disease among young adults using creatinine-based glomerular filtration rate-estimating equations. Nephrology Dialysis Transplantation 2010;25(12): 3934-3939. Risk factors for CKD, such as hypertension and diabetes were common among these patients.

Although additional research is needed to fully understand the significance of glomerular hyperfiltration, its believed to be associated with an increased risk of kidney damage. PMID 21151533. Higher serum creatinine concentrations in Black patients with chronic kidney disease: Beyond nutritional status and body composition. Their main job is to filter wastes and extra water out of your blood to make urine. In 1998, before the development of common eGFR formulas, results from the National Health and Nutrition Examination Survey found that, on average, Black people had higher serum creatinine levels than people of other races. Black Doctors USA states that racial biases cause an increased risk of chronic conditions in Black and other marginalized communities. If your eGFR has changed, your healthcare team may want to make changes to your treatment plan. Levey AS, et al. Levey AS, et al.

Reassessing the inclusion of race in diagnosing kidney diseases: An interim report from the NKF-ASN task force. While creatinine production can vary by individual, high levels in the blood can potentially indicate decreased kidney function. One advantage of cystatin C as a biomarker is that its levels are not dependent on an individuals muscle mass or diet, and studies have borne out that race and body surface area need not be factored into equations utilizing cystatin C to calculate eGFR.15 There remain concerns about the accuracy of cystatin C, particularly in the setting of comorbid heart and liver disease which are both common in patients with CKD.16. eGFR will be reported with one value as GFR Calculation (GFR CALC). eGFR 15-29, severe kidney damage. What is CKD? African American people typically have higher eGFR scores than people of other ethnicities. (2017). Chapter 1: CKD in the General Population.
