How could eGFR numbers go up if you have chronic kidney disease?

Trying to figure out how this works
Thanks

They fluctuate according to many factors, including hydration, probably time of day (it seems), and muscle use (I was told).

My docs told me that the eGFR based on creatinine is sensitive to muscle wasting and weight loss. The Cystatin C eGFR is a better measure, I was told.

@jessgarduno30 Welcome to Mayo Clinic Connect. The GFR and eGFR are measurements of how well the kidneys are functioning. It is affected by so many things. A one time lab result is less informative than the trend in results over time. If you don’t mind sharing, may I ask why you are interested in GFR? Are you concerned about yours?

Thank you for replying first

So back story albumin in urine went form 1. To .4
Creatinine urine went form 216 to 74. Creatinine in blood went from .77' to .79' .69' .66
Alkaline phosphate 74' 66' 62'60' 51. Platelet count 280' 335' 306' 369 'vitamin d 2017 was 26 now 18

Thought you couldn't repair kidney damage?

It's kidney disease. And yes it can improve. I have been told hydration is very important, as well as avoiding certain meds (NSAIDS). Only use tylenol. Other issues with salt, blood pressure, potassium, protein in diet etc. etc. and recommendations are different for each of us.

If you were at all dehydrated for the first test, that would make your eGFR worse. Do you have a Cystatin C done?

Your vitamin D is very low. Is your doc dealing with that?

Sorry I took my might pills and won't be up long. But thanks for relaying I hear low vitamin d is part of Kidney disease

Nut if my numbers are getting better how can other numbers be goi g the wrong way

Not sure what you mean. Maybe you can post tomorrow and explain!
