Julie,
Congratulations on the kidneyversary.
I had my own 8-month follow-up visit in May. Before the visit, I was very concerned that my creatinine was, not only much higher than it had been pre-donation (I mean, I realized I only had one kidney now, and had half the "kidney power", etc.), but it was even slightly higher than it had been right after the surgery. That, I really didn't like.
However, the nephrologist told me the slight increase since right after the surgery meant essentially nothing, and I was in good shape in that regard. And: my creatinine pre-surgery and at my 8-month follow up were very similar to what yours are.
I'm not commenting about the GFR, because I'm always a little confused about how my lab reports mine.
I hope everything works out for you but, at least creatinine-wise, that doesn't sound too bad at all (but I'm not a physician).
Be well, Snoopy
