Thanks, Catmiaow111.
That's really interesting, Daibell. I thought I'd read that 14 hours was ideal and 12 hours the minimum.
I've requested Fasting Glucose, HbA1C, full lipid profile as well checks for B12 and iron deficiency.
Asked the receptionist to check with the doctor that it was OK to have them all but she said might as well as I was coming in anyway!
Getting weight and blood pressure checked too!
