What’s searchable?G6PC2 participates in glucose handling in pancreatic beta cells.
G6PC2 encodes a glucose-6-phosphatase-related protein expressed in pancreatic islet cells. Common variation is associated with differences in fasting glucose regulation; it is not the insulin receptor.
Normal <100; prediabetes 100-125; diabetes ≥126 on confirmatory testing unless unequivocal hyperglycemia.
Ask your clinician to read this result with concurrent glucose, kidney function, and exogenous insulin use.
Diabetes may be diagnosed at ≥200 with classic symptoms or hyperglycemic crisis.
Normal <140; prediabetes 140-199; diabetes ≥200.
No universal reference or treatment target. Standardize fasting duration and collection time.
Renal threshold, SGLT2 inhibitors, pregnancy, and hyperglycemia matter.
Dr. Purser shares the benefits of fasting in everyday life. Have you ever tried a 72-hour fast? The benefits of fasting include reduction of premalignant stem cells and chance of cancer. Learn why cancer cells require glucose and how fasting reduces lipids and inflammation. Dr. Purser also discusses the need for careful monitoring of diabetic patients who choose to fast. Learn about precautions of fasting and the need to intake fluids, electrolytes, vitamins, and medications. Contact us at (801) 796-7667 or info@danpursermd.com for help.
