Hypoglycemia Answer A16687
Hi, welcome to the ehealth forum and I am glad to help you.
You seem to be concerned by the interpretation of oral GTT in diagnosing hypoglycemia.
A traditional method for investigating suspected hypoglycemia is the oral glucose tolerance test(as you have undergone), especially when prolonged to 3, 4, or 5 hours. Although quite popular previously, repeated research studies have demonstrated that many healthy people will have glucose levels as low as 43mg/dl during a prolonged test, and that many types of significant hypoglycemia may go undetected with it. This combination of poor sensitivity and specificity has resulted in its abandonment for this purpose by physicians experienced in disorders of glucose metabolism. Most doctors nowadays agree that Whipple's triad is more appropriate for the diagnosis of hypoglycemia.
Hope this helps. Take care.
