Diagnosing Type 1 diabetes in children can be a complex process, but early detection is vital for effective management.
When a child shows symptoms of high blood sugars, as discussed in detail in Part 1, a healthcare professional will conduct a thorough medical history and physical examination. There are some diagnostic blood tests that can be done, typically providing results within minutes. These include: a fasting or random glucose level, an oral glucose tolerance test, an A1c, and/or an autoantibody test.
A glucose level portrays what the patient’s glucose level is at that moment of the blood being drawn. A fasting blood sugar greater than 100 mg/dl or random nonfasting blood glucose greater than 140 mg/dl is considered elevated. Glucose levels can increase to extremely high levels in undiagnosed Type 1 patients, often greater than 250 mg/dl, and even up to 1,000 mg/dl.
