Insulin is a hormone produced in the pancreas that is responsible for carrying glucose (blood sugar) from the bloodstream into the cells where it is converted into fuel for body functions. Good health and energy depends upon the body’s ability to make and use just the right amount of insulin to keep our blood sugar at optimal levels and our metabolism working normally. Every cell of the body has receptor sites that allow insulin to open the door of the cell so that glucose can enter and go to work. If the body builds up a surplus of glucose, usually from high caloric intake of sugar and carbohydrates that are not burned up through regular exercise, the cells become overloaded and cannot accept more blood sugar. The door is closed. The cells have in effect become resistant to insulin’s attempt to provide them with more glucose. In this scenario, blood levels of insulin and glucose reach and remain at unnaturally high levels, leading to obesity, high blood fats and a heightened risk for diabetes. Blood spot testing of Fasting Insulin levels (using a nearly painless finger stick) to collect a few drops of blood which are then dried and mailed in to our lab, can detect excess insulin in the blood stream to provide an early warning system for prevention of insulin resistance and diabetes. Candidates for Fasting Insulin testing in blood spot include: individuals with known/suspected hypoglycemia, insulin resistance, pre-diabetes, family history of diabetes, overweight or obese, women with irregular menses, scalp hair loss, increased facial/body hair, polycystic ovary syndrome, individuals with symptoms of anxiety, palpitations, fatigue, profuse sweating, irritability, weakness, shakiness, dizziness, food and sugar cravings and central obesity. Early detection of insulin resistance through blood spot testing is the key to prevention of harmful changes in the body, leading to diabetes.
