What about an eight year old child who suddenly developed diabetes and whose glucose is not regulated, ranging from 70 to 200 mg/dl [3.9 to 11.1 mmol/L]?

If I understand your question, you are asking about blood glucose readings that go quickly from 70 to 200 mg/dl [3.9 to 11.1 mmol/L]. How long apart are the two readings? If there are more than a few hours between them, this happens quite frequently. If they are close together (within two to four hours), then the question is what was the blood sugar half an hour or one hour prior to the 70 mg/dl [3.9 mmol/L]. Maybe, it was low and this caused some rebound hyperglycemia as the body tried to correct the low sugar level, and then overshot. Also, is it possible that the 70 mg/dl [3.9 mmol/L] was a falling blood sugar that would have been 40 or 50 mg/dl [2.2 or 2.7 mmol/L] in another 30-60 minutes?

Lastly, perhaps a normal blood glucose of 70 mg/dl [3.9 mmol/L] followed shortly by a blood glucose of 200 mg/dl [11.1 mmol/L] is merely too much carbohydrate and insufficient insulin. More frequent blood glucose monitoring and strict adherence to a meal plan with minimal variation in time of insulin, site of insulin, foods ingested, etc. should answer this question when you analyze the results with your diabetes team.
