I am almost 90 yrs old and have had CKD for many years. My gfr is down to 14 but in one yr has gone back and forth between 18 and 14. What makes the difference in those numbers that I can control?

The results that you mention for the variability of your estimated glomerular filtration rate (eGFR) are within the range of variation for the test. This variability is very normal and does not mean that your kidney function is that much different from one test to the next. I do not think there is anything you can do that would significantly change these tests. You should follow your doctor’s advice.
