Sugar Test
A blood glucose test measures the level of glucose (sugar) in your blood. The test can involve a finger prick or a blood draw from your vein. Healthcare providers most commonly use blood glucose tests to screen for Type 2 diabetes, which is a common condition.
Glucose (sugar) mainly comes from carbohydrates in the food and drinks you consume. It’s your body’s main source of energy. Your blood carries glucose to all of your body’s cells to use for energy.
Several bodily processes help keep your blood glucose in a healthy range. Insulin, a hormone your pancreas makes, is the most significant contributor to maintaining healthy blood sugar.
If you have elevated blood glucose levels , it usually indicates diabetes. Diabetes develops when your pancreas doesn’t make any insulin or enough insulin or your body isn’t responding to the effects of insulin properly.
