![]() ![]() The equation does not require weight because the results are reported normalized to 1.73 m² body surface area, which is an accepted average adult surface area. Caution: eGFR calculator results may not be accurate if you are older than 70, younger than 18, vegetarian, pregnant, very overweight, very muscular. This eGFR calculator uses the MDRD 4 revised formula to estimate GFR. It is NOT to be used for patients with acutely declining renal function or increasing proteinuria. It is removed by healthy kidneys and can build up in your blood if your kidneys are not working well. Disclaimer: The Kidney Failure Risk Equation (KFRE) is for patients with Chronic Kidney Disease Stages 3-5 (eGFR <60). Min indicates the minimum of S cr/κ or 1, and Age Sex Male GFR (Ml/Min/1.73M2) Urine Albumin: Creatinine Ratio (mg/mmol) Calculate. This calculator provides estimated times to when a patient may require renal replacement therapy or when. Α is -0.329 for females and -0.411 for males, Pediatric Chronic Kidney Disease Risk Calculator. Κ is 61.9 for females and 79.6 for males, This equation is recommended when eGFR values above 60 mL/min/1.73 m² are desired. This CKD-EPI equation calculator should be used when S cr is reported in µmol/L. ![]() All laboratories should be using creatinine methods calibrated to be IDMS traceable. different laboratories may use a different formula to calculate the eGFR. The NIDDK’s calculators rely on creatinine determinations which are isotope dilution mass spectrometry (IDMS) traceable. Additional indicators or renal disease should also be sought in these patients. The default value of 1. Modification of Diet in Renal Disease (MDRD) Study equation 2. Typical physical activity level numbers range from 1.4 (sedentary) to 2.5 (very active). In adults, the most widely-used equations forĮstimating glomerular filtration rate (GFR) from serum creatinine are theĬhronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation 1Īnd the isotope dilution mass spectrometry (IDMS) traceable Once guidance is adopted, we will update this content accordingly. Why is Patient Education Important to your Health While conversations with your healthcare provider are important, researchers have found that people who have increased access to health information are better able to make improvements to their health. Recommended eGFR equations will be changing. If you dont know your kidney number, you can use the GFR Calculator here. ![]()
