Final answer:
The hemoglobin A1c level, which should be less than 7%, is indicative of good metabolic control for a child with type 1 diabetes, reflecting the average blood glucose level over the previous 3 to 4 months and corresponds with a lower risk of complications.
Step-by-step explanation:
Your question pertains to identifying a laboratory result that indicates good metabolic control for a child with type 1 diabetes. The key laboratory test that reflects good metabolic control in those with type 1 or type 2 diabetes is the hemoglobin A1c level.
A normal hemoglobin A1c level is less than 7%, which reflects the average blood glucose level over the past 3 to 4 months. Good control is usually indicated when the hemoglobin A1c is close to the normal range, particularly for diabetics.
A lower hemoglobin A1c level correlates with a reduced risk of complications associated with diabetes, such as issues affecting the eyes, kidneys, and nerves. Therefore, regular monitoring of hemoglobin A1c is an important aspect of diabetes management.
