[QUOTE="Bluetit1802, post: 1637118, member: 94045"] My UK surgery no longer does fasting blood glucose tests, even on non-diabetics having routine health checks. They just do an HbA1c. Fasting BG tests might indicate a possibility of diabetes/pre-diabetes, but are no longer used for diagnosis without an HbA1c . They have to be followed up with an HbA1c, and unless that is sky high, a second HbA1c a week or two later. Sometimes an OGTT is used aswell as or instead of an HbA1c. Any number of factors influence the fasting BG levels, such as anxiety, stress, disturbed sleep, rushing about at home then getting to the surgery, driving, waiting in the waiting room. They all affect it. You would do well, as suggested, to buy your own meter and start testing at home as soon as you get out of bed and wash your hands. [/QUOTE]
