victorqedu Posted August 6, 2020 Share Posted August 6, 2020 Hello I'm trying to calculate eGFR using the CKD-EPI formula but my results are wrong and don't know why. I use this site to check my results: https://qxmd.com/calculate/calculator_251/egfr-using-ckd-epi And I use this site for a very simple formula: https://www.niddk.nih.gov/health-information/professionals/clinical-tools-patient-management/kidney-disease/laboratory-evaluation/glomerular-filtration-rate/estimating I'm testing on a white male 40 years of age and with serum Creatine 51 so the formula is: GFR = 141 × (Scr/0.9)-1.209 × (0.993)Age I calculated in many ways, this test is done directly at Postgsql database level: SELECT 141*POWER(51.0/0.9, -1.209)*POWER(0.993, 40) The result is 0.80 but the correct result should be 127.8. All values I checked give me a subunitary value and this is wrong. What do I apply wrong in the formula? Thank you. Link to comment Share on other sites More sharing options...
