Estimated GFR (eGFR) using Modification of Diet in Renal Disease (MDRD) formula. Your kidney function is determined by how well these filters are working. identified on a renal biopsy). We've also listed some additional information to provide you with context, below. The patient is > 18 years of age. pathological abnormalities (e.g. We used to calculate all the GFRs as fellows at Albert Einstein in the Bronx, New York. Your eGFR is roughly equivalent to the degree of kidney function you have, so an eGFR of 60 would mean that your kidneys are only working at about 60%. The National Kidney Foundation recommends using the CKD-EPI Creatinine Equation (2009) to estimate GFR. Not yet validated in COVID-19 Ranson's Criteria Estimate mortality in patients with pancreatitis. eGFR using CKD-EPI Formula (on-line calculator - from Kidney Health Australia) The CKD-EPI formula has varying coefficients depending on the sex and serum creatinine of the patient as shown below.
