For the first method, blood samples were collected in tubes containing sodium fluoride (NaF), a glycolysis inhibitor. The body tightly regulates blood glucose levels as a part of metabolic homeostasis. This is because these two different pieces of technology measure glucose from different sources (blood versus interstitial fluid), and blood glucose changes a little before interstitial fluid glucose. "They really help the physicians and educators if we’re trying to look at whether you need to have your medication, insulin or mealtime adjusted," says Palmer. Normal blood sugar levels for diabetics before eating (fasting) range from 80 mg/dL to 130 mg/dL while the high range starts at 180 mg/dL. Different Reading By Blood Glucose Meter.
