This happened to me, so I became suspicious of Amazon. I back-checked prices of items in my cart against those of an Incognito Browser (so they wouldn't know it was me). My prices always start higher, but eventually come down to that of the Incognito Browser's after a week or two.
Your doctor may suspect that you have diabetes if your blood sugar level is higher than 200 milligrams per deciliter (mg/dL). To confirm the diagnosis, one or more of the following tests must be done. Fasting blood glucose level: Diabetes is diagnosed if it is higher than 126 mg/dL two different times.
The normal blood glucose level (tested while fasting) for non-diabetics, should be between 3.9 and 5.5 mmol/L (70 to 100 mg/dL). The mean normal blood glucose level in humans is about 5.5 mmol/L (100 mg/dL); however, this level fluctuates throughout the day. Blood sugar levels for those without diabetes and who are not fasting should be below 6.9 mmol/L (125 mg/dL).
