Many surgeries prefer to give you your results in person, so that they can be discussed with you.
Unfortunately that does mean you have to wait until there’s an appointment available!
The reassuring thing, I suppose, is that they aren’t treating the situation as urgent, and are happy for you to be seen in a little while - so whatever your results I guess they don’t feel you are in immediate peril. Diabetes, particularly T2, can be a fairly slow-moving foe.
Hope you are able to get some good advice on Wednesday, and are given a clear way forward. Do ask for the actual numbers (and units) of any checks you had done, as this can help you research and understand exactly where you are starting from.
