Assessing glomerular filtration rate (GFR) using kidney filtration markers in blood is the test means for determining kidney function, diagnosing kidney disease and measuring its progression. A higher filtration rate indicates healthy kidney function, while a lower rate points to various stages of kidney disease. A new study led by researchers at the Johns Hopkins Bloomberg School of Public Health found that the new CKD-EPI equation for calculating GFR is a better predictor of risk for kidney disease and death compared to the most widely used method. The findings suggest that switching to the CKD-EPI equation for calculating GFR could focus efforts more efficiently, and improve estimation of patient future risk and care of kidney disease. The study is published in the May 9 edition of JAMA.
