The HbA1c test is an important tool used for the screening, diagnosis, and management of diabetes.Ĭholesterol is a waxy, fatty substance found in the blood that is needed to make cell walls, tissues, hormones, vitamin D, and bile acid. When sugar enters the bloodstream, it attaches and sticks to hemoglobin molecules to form hemoglobin A1c. Hemoglobin is a protein found in red blood cells that carries oxygen from your lungs to the body's tissues and returns carbon dioxide from the tissues back to the lungs. Insulin resistance, a precursor to type 2 diabetes, is strongly associated with atherosclerosis (hardening of the arteries caused by plaque accumulation in the inner lining of an artery). In type 2 diabetes, the cells become resistant to insulin and ignore its message to absorb glucose, a condition known as insulin resistance. In people with diabetes, insulin is either less effective or not produced in sufficient quantity, making it harder to manage the amount of sugar passing through the blood. Consistently high blood glucose is typically seen in individuals with uncontrolled or undiagnosed diabetes. Blood glucose levels are tightly controlled by hormones like insulin, which is produced in the pancreas. The sugar mainly comes from the food you eat and supplies energy to all cells in the body. Glucose is the main sugar found in your bloodstream. Important!
