@cekkk No apologies needed for being wordy! I echo the welcome to Mayo Clinic Connect, and am glad you sought us out.

As a fellow kidney disease patient, it has been important for me to understand that trends in labs results, instead of a single lab, is better for an overall picture of your kidney health. Due to your hydration level, general health, different machines processing the specimens, and even time of day, the results can flucuate. And as @collegeprof mentioned, medications. I also took Torsemide for a short time; it was not good for me and returned to furosemide.

Diabetes and high blood pressure seem to be the leading cause of kidney issues, and I hope your endocrinologist is also aware of what your recent labs show, so they can confer with your primary doctor.

Please do let us know what comes of all this, and remember to come and ask us questions!
