Question
An 11-year-old child has been diagnosed with diabetes, but it is unclear whether it is Type 1 or Type 2. The child has undergone a serum test, which showed that the anti-glutamic acid decarboxylase antibodies, insulin cell antibodies, and insulin autoantibodies were all negative. The glucose tolerance test result was 2, and there was a history of diabetic ketoacidosis. How can one determine whether it is Type 1 or Type 2 diabetes?
Answer
Further examination of blood insulin and C-peptide levels is needed. If these values are low, it may indicate Type 1 diabetes.
