Blood sugar test A blood glucose test measures the amount of a sugar called glucose in a sample of your blood. Glucose is a major source of energy for most cells of the body, including brain cells. Carbohydrates are found in fruit, cereal, bread, pasta, and rice. They are quickly turned into glucose in your body. This raises your blood glucose level. Hormones made in the body help control blood glucose level. Blood sugar Fasting (BSF):- The test is done in the morning, before the person has eaten. The normal range forblood glucose is 70 to 100 mg/dl. Levels between 100 and 126 mg/dl are referred to as impaired fasting glucose or pre-diabetes. Diabetes is typically diagnosed when fasting blood glucose levels are 126 mg/dl or higher. Blood sugar postprandial (BSPP):- A postprandial glucose test is a blood glucose test that determines the amount of a type of sugar, called glucose, in the blood after a meal. Glucose is mainly made from carbohydrate foods. It is the main source of energy used by the body. Normally, blood glucose levels increase slightly after eating. Random Blood Glucose Test:- A random blood glucose test is used to diagnose diabetes. The test measures the level of glucose (a type of sugar) in your blood. If your blood glucose level is 200 mg/dL or higher and you have the classic symptoms of high blood sugar (excessive thirst, urination at night, blurred vision and, in some cases, weight loss) your doctor may diagnose you with diabetes. If you do not have any symptoms of high blood sugar, your doctor will probably have you take another test for further evidence of diabetes.1 Usually, having high blood glucose can be a sign that your body is not functioning normally and that you may have diabetes. If you have high blood glucose and it is not treated, it can lead to serious health complications. However, finding out that your blood glucose is elevated is powerful information that you can use to keep yourself healthy. If you know that your blood glucose is high, you can take steps to lower it, by losing weight (if you are overweight or obese), getting regular moderate physical activity, and taking a medication that lowers blood glucose.2 Hemoglobin A1c (HbA1c):- Hemoglobin A1c, often abbreviated HbA1c, is a form of hemoglobin (a blood pigment that carries oxygen) that is bound to glucose. The blood test for HbA1clevel is routinely performed in people with type 1 and type 2 diabetes mellitus. BloodHbA1c levels are reflective of how well diabetes is controlled Insulin:- A hormone produced in the pancreas by the islets of Langerhans, which regulates the amount of glucose in the blood. The lack of insulin causes a form of diabetes. o an animal-derived or synthetic form of insulin used to treat diabetes. C-Peptide:- A C-peptide test measures the level of this peptide in the blood. It is generally found in amounts equal to insulin because insulin and C-peptide are linked when first made by the pancreas. Insulin helps the body use and control the amount of sugar (glucose) in the blood.
