Question

Which of the following methods can be used to obtain a definitive diagnosis of type I insulin–dependent diabetes?

• A. Detecting the presence of islet cell antibodies.
• B. Performing an insulin receptor count.
• C. Testing for elevated blood sugar concentration.
• D. Screening individuals for obesity.

Answer 1

The correct option is A

Detecting the presence of islet cell antibodies.

The beta cells of the islet of Langerhans produce Insulin which helps in controlling the blood sugar levels. In type I diabetes, the body's immune system attacks and destroys the beta cells. Antibodies against the beta cells are present in the islets. Thus, detecting the presence of these antibodies can be a definitive diagnosis of type I insulin-dependent diabetes.
