A blood glucose test mainly screens for diabetes by measuring the level of glucose (sugar) in your blood. It can be a blood draw or a finger prick.
Glucose is a sugar with the molecular formula C 6 H 12 O 6. It is the most abundant monosaccharide, [4] a subcategory of carbohydrates. It is made from water and carbon dioxide during photosynthesis by plants and most algae.
Learn how your body uses glucose and what happens if your blood glucose levels are too high, how it's made and how it is consumed by the body
Learn about glucose blood tests and how and why to do them. Plus, find out why a person should keep their blood glucose levels within a healthy range.
