Mine are all back after about a week - the HbA1c takes longest. I go to the practice and ask at reception for a full print-out of them, which I now get without much difficulty - sometimes I have to train a new receptionist!
Once I've had a look at them, if there's anything I want to talk about I go to see my "own" GP. Because he know most about me as I tend to go only to him, it seems most logical to discuss things with him. I think that if there was anything that really troubled the Diabetes Specialist GP I'd get called in, but we do tend to avoid each other if possible.
I would be happy to see our practice nurse 'cos she knows a lot, but like you, the GPs review the results. Why not ask if your results are back in about a week's time, and then make an appointment with the doctor?
