IA2 (Insulin Autoantibodies)
The IA2 (Insulin Autoantibodies) test is a blood test that detects autoantibodies against the IA2 protein, a key component of insulin-producing beta cells in the pancreas. This test helps identify autoimmune activity that may damage beta cells and is primarily...

Understanding IA2 (Insulin Autoantibodies)
IA2, also known as islet cell antigen-2 (ICA-512), is a protein located on the surface of insulin-producing beta cells in the pancreas. It plays an important role in regulating insulin secretion. In type 1 diabetes, the immune system mistakenly attacks and destroys these beta cells, leading to insulin deficiency. During this autoimmune process, the body produces IA2 autoantibodies, which are detectable in approximately 50–75% of individuals with T1D at or before disease onset. The IA2 (Insulin Autoantibodies)...
What does IA2 (Insulin Autoantibodies) measure?
The IA2 (Insulin Autoantibodies) test is a blood test that detects autoantibodies against the IA2 protein, a key component of insulin-producing beta cells in the pancreas. This test helps identify autoimmune activity that may damage beta cells and is primarily used in the diagnosis and prediction of type 1 diabetes (T1D).
