@nscappa It would be advisable to be aligned with a nephrologist. Good idea, and as you know, there is so much to consider as we journey through kidney disease!

Several factors to think about while you ponder why the drop in eGFR:
-Hydration plays a big part in healthy kidney function. Getting enough fluids into you on a daily basis goes a long way to keeping your kidneys happy. Dehydration can cause a drop in value.
-Look at trends of your labs, not a single lab result.
-Has there been any change in medications recently? Or change in other health conditions?
-Differences in processing labs and their machines can give you different results. For example, the on-site lab at my oncology center gives me a different eGFR value than the commercial lab where my "regular" labwork is done.

Are you able to self-refer to a nephrologist, or are you at the mercy of your doctor sending you to one? It would most likely ease your mind to see a specialist when you can get in!
