Hi, I have just collected a form from my doctor's surgery for my routine HbA1c blood test. I have noticed that a tick has been put next to UE - Electrolytes. I don't know why this has been ticked. I am a LCHF diet and exercise controlled Type 2 diabetic. I feel really well and have only visited my doctor this year about my diabetic diagnosis and related tests, all of which were fine. Any ideas/ advice?
