Fasting GlucoseFasting glucose measures the sugar in your blood after an overnight fast. It is one of the main tests used as part of screening for pre-diabetes and type 2 diabetes — checking how well your body handles blood sugar when it has had nothing to work with for 8 hours. A single result is a snapshot; your GP usually looks at it alongside a longer-term blood-sugar average before drawing any conclusions.Fasting InsulinInsulin is the hormone that controls your blood sugar. You are probably hoping for a clear "is my number OK?", and the honest answer is there is no single agreed normal range. A high fasting level can be an early sign your body is needing more and more insulin to do the same job — but it is a prompt for a chat with your GP, not a diagnosis.HbA1cHbA1c tells you what your average blood sugar has been over the past 2–3 months — not just where it sat this morning. That makes it far more useful than a one-off fasting test for understanding your risk of diabetes or how well it is being managed. Australian labs print the result in two units (a percentage and a number in mmol/mol) so you may see both on your report; they mean the same thing.
