Hi Lazza,
What are the symptoms present? I understand your concern regarding this and I agree with your attending physician that a repeat test may be necessary and depending on the results, a referral to a nephrologist may need to be done. Chronic kidney disease slowly gets worse over months or years and loss of kidney function may be so slow that you do not have symptoms until the kidneys have almost stopped working. It is important to prevent the final stage of chronic kidney disease or end-stage renal disease (ESRD). It is best that you check with the specialist for proper management. Take care and do keep us posted.
Thank you for your response! As for symptoms, I have none ... or at least nothing I would associate with kidney problems. The only thing close are symptoms from an enlarged prostate, something I have been dealing with for 15 years (.. I am not on any medication for this). Oh, I do see that sleep difficulties might be a symptom. I have suffered from intermittent sleep since forever.
Again, I really don't want to go through unnecessary extensive (and expensive!) tests. I still find it hard to imagine that after having stable (, albeit somewhat deficient,) kidney function for 20 years that there is now a need to see a nephrologist.

Well I went and got more blood work done. I was told my results were now "near normal" and there is no need to see a nephrologist. Since my eGFR was 58 before it probably popped up to 59, which really isn't a statistically significant change. But it's enough for my doctor to just say drink more water and I'll see you next year.

PS - this time before the blood work I made extra sure I was well hydrated. It might have helped!
