- Revised Bedside Schwartz Formula (For ages 1-17)
- Cockcroft-Gault Formula
- CKD-EPI Cystatin C 2012 Equation
- CKD-EPI Creatinine - Cystatin C 2021 Equation

Also includes information on:

-Glomerular filtration rate (GFR)
-Chronic kidney disease (CKD)
-Clinical use on how to test, evaluate, and slow progression

CKD pt + former Med Professional

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.

eGFR but no BSA

This gives you the current 2021 CKD-EPI calculator, however, it does not include the ability to factor in BSA (body surface area - height/weight). 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.
