The National Kidney Foundation web site has the 2021 calculator with the ability to include BSA. If you do not factor in BSA, you may get a less precise eGFR value. Most national labs also do not factor in BSA, so you might have a conversation with your physician to see her/his thoughts. Just accepting the basic CKD-EPI 2021 formula, may place you in a GFR category and ACR category, you do not deserve. The discussion within this app notes the necessity to factor in BSA to the CKD-EPI 2021 equation, but the equation included with this app does not allow this option. ### 1/5 — Não está fazendo cálculos *2021-10-04* Está impossível de usar depois da atualização! A vírgula entre os números não sai! (,) e o cálculo sai errado ficou péssimo ### 1/5 — Error *2021-09-30* We can’t introduce decimals in creatinine data!!! It’s a bug?? ### 5/5 — Help *2021-09-28* We can’t introduce the coma in creatinine data. ### 3/5 — Não é possível digitar o valor correto da creatinina e outros *2021-09-27* Pelo no iPhone com iOS 15 , não é possível digitar o valor numérico correto , apenas inteiros ( creatinina 1.5, digita-se apenas 15 ) , gerando cálculos incorretos ### 1/5 — Utterly useless unlike the calculator on their website. *2021-06-04* I need - no, REQUIRE - a GFR calculator that lets me individualize results to my patient’s individual height and weight. Too many of my patients are way off of ‘standard’ parameters for that to make sense. I had an ancient app that would do this but it no longer works on the current iOS upgrade. I was hoping this app would do so since the cGFR calculator on their website has that as an option. No such luck - and that makes this app useless to me. It was removed immediately after downloading. ### 3/5 — Confusion *2020-12-09* Just clear when we select male/female and black/other the grey option is selected one or the white one? ### 3/5 — Nurse *2019-08-14* Very handy, but there is a flaw that must be addressed. The race and sex fields change when they should not. Tap on “male” for example and tap on on it a second, third, fourth time. Why does it change back and forth and back and forth? Please fix that behavior. Thanks. ### 5/5 — Excellente *2019-05-03* La plus simple d’usage et très propédeutique . Un référence ### 5/5 — CKD pt + former Med Professional *2017-10-30* I wish I’d known about this several years ago-it would have saved a few grey hairs. I’m 57, a former RN-Paramedic who had to leave Medical School in my final year due to growing health issues related to my genetic disorder, nail-patella syndrome. I (and mySon) were also born with just 1, affected kidney. It wasn’t until the last two years that the proteinuria and overall function began to decline. Because I’m not a transplant candidate, we’re keeping an extremely close eye on everything. Thank you for making this available-AND for everything else you guys do to help patients like myself!! PS I sent the link to this app to my primary & nephro -neither of whom had been previously aware of it. ## Frequently asked questions about eGFR Calculators ### What is eGFR Calculators? eGFR Calculators is a free medical application developed by the National Kidney Foundation.
