Hi @
Doughnut123 , and welcome to a really great forum.
When your first diagnosed it really takes some time to get your head round it all, even coming on here and everybody welcoming you can seem a little odd at first because it is some where you did not expect to be.
I t really does appear that you have had a HbA1c blood test, and before you go rushing off to Asda, if you go back to the Doctors and ask the receptionist if you could have a 'Print Out' of you HbA1c test. If she gives you that then you will know that you have been tested and the figure you have been quoted is actually a %. That 6.7% is not too high but certainly enough for diagnosis and medication to start.
Just slow down it can be very overwhelming at first as sometimes they are not particularly many symtoms for you to believe that you can have diabetes.
Keep asking the questions and read and learn from here it will be very helpful for you.
