correlation between creatinine and eGFR

I always learn a lot when someone poses a question because I go look for research.
Looks like creatinine often doesn’t rise much at the beginning of a change in kidney function. So you may have caught it early. Or possibly your muscle mass has remained high (increased lately?) that would keep creatinine high. I’m certainly no expert, and only looking through research as I also have had changes in scores lately.
For people with diabetes 2, a drop in eGFR of 7.6% looks significant. So much depends on where your health is now, including weight and diet changes.
Here’s the articles I was reading. You may already have this info, but I thought I’d send it along.
Medscape sometimes requires a log in to access, but this looks like it’s open to the public, about creatinine:

Sorry I couldn’t be more helpful!

Thank you for those links! This one just gave me an insight as to why my creatinine levels are high, possibly. I intermittent fast! I have for years. This link suggests fasting can cause a rise in creatinine levels. My C Cystatin blood test results recently gave me a healthier result and put me in 3rd stage rather than 4th. The article suggests creatinine tests are false levels of creatinine. Now I wonder if intermittent fasting damages kidney function or if it's a false indication of kidney getting worse.
