No worries. Like you, I was keen to know as soon as possible as to when I could get my medical back!
The bloods are all covered by the NHS. They are the exact same as required from any other diabetic. Eye and feet screening too. The only added extra that non flying diabetics don’t need is a stress ECG. So whilst the 90 days was ticking by, I enjoyed the summer off from commercial flying and got my eyes, feet and stress test all done. In the final week approaching the 90th day, I got the bloods done so it was sent away on the evening of the 90th day.
All this is from a new diagnosis of insulin dependant diabetes. T2 on oral medication could possibly result into a streamlined process to regaining your medical.
I found the CAA to be very proactive with it all.
