After donating a kidney  (3 weeks ) my GFR came back as 52.  should I be concerned or is that normal?

In brief: About right.

It is age and body size dependent.
Considering most kidney donors have a GFR of 80 to 120 cc/min when they donate, and lose about half of the GFR when they donate, yours is about right. In reality donors <55 years will demonstrate some hypertrophy of the remaining kidney, and have about 60-70% of their pre donation level of renal function within a few months after donation

In brief: Maybe

Lets say normal gfr=100.
You donate kidney. Immediately you have gfr=50.Over time, remaining kidney should filter more and GFR increases on average to 76. It is possible that this will take longer for you. Or you may remain with 52.(you can live forever with 52 with no problem) overall, survival and quality of life for donors is same/better than nondonors; i wouldn't worry; recheck in 3 months.
