We link primary sources - including studies, scientific references, and statistics - within each article and also list them in the resources section at the bottom of our articles. Medical News Today has strict sourcing guidelines and draws only from peer-reviewed studies, academic research institutions, and medical journals and associations. The NKF aims to keep assessing these equations to ensure that they are as accurate as possible. Cystatin C is a protein that the kidneys filter out of the blood. The task force also recommended using cystatin C to calculate eGFR. For this reason, they recommend using a new 2021 CKD-EPI creatinine equation to calculate eGFR, which excludes ethnicity as a factor. ![]() In September 2021, the NFK and ASN task force released a report suggesting that these equations overestimated GFR in African American people and, to a lesser extent, non-African American people. These equations take into account a person’s creatinine levels, age, sex, and ethnicity. Scientists then use the MDRD or CKD-EPI equation to calculate the person’s eGFR score. 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.īoth equations involve taking a blood sample from a person’s arm to send off for testing. They proposed a new approach to estimating eGFR in September 2021. The National Kidney Foundation (NKF) and the American Society of Nephrology (ASN) formed a joint task force in 2020 to review the use of race and ethnicity in these calculations. ![]() This is why they typically provide separate results for African American and non-African American people in their reports. However, laboratories are not always aware of the person’s ethnicity when they receive a blood sample. This can help the eGFR score provide a more reliable indication of kidney functioning to guide diagnosis and treatment decisions. It is important to mention that these factors are likely due, at least in part, to health inequities and structural racism in the medical community.īecause of these health concerns, some calculations to determine eGFR include race or ethnicity as a factor. This means that they often have higher eGFR scores than people from different ethnic backgrounds. They also typically have elevated creatinine levels in their blood. Why do eGFR reports include African American and non-African American results?Īfrican American people have an increased risk of kidney disease due to higher rates of diabetes, high blood pressure, and heart disease.
