Overview:
Investigate autoimmune type 1 diabetes with a comprehensive antibody blood test.
The Type 1 Diabetes Mellitus – Autoantibodies Test measures key antibodies associated with autoimmune destruction of insulin-producing pancreatic cells.
This advanced antibody blood test for type 1 diabetes may help support the diagnosis of type 1 diabetes mellitus and assist healthcare professionals in distinguishing autoimmune diabetes from other forms of diabetes.
Your test includes analysis of:
- GAD65 antibodies
- IA2 antibodies
- IAA (Insulin Autoantibodies)
- ZnT8 antibodies
This test is best combined with the Diabetes Blood Test Panel to enhance diagnostic accuracy.
All results are doctor-reviewed and explained in a clear, easy-to-understand report.
What Is a Type 1 Diabetes Antibody Test?
A type 1 diabetes antibody blood test checks for autoimmune markers linked to type 1 diabetes mellitus.
In autoimmune diabetes, the immune system mistakenly attacks insulin-producing beta cells in the pancreas. Antibody testing may help identify whether this autoimmune process is occurring.
This test may be recommended if:
- You have symptoms suggestive of diabetes
- Your healthcare professional wants to distinguish type 1 from type 2 diabetes
- You have unexplained high blood sugar
- You have a family history of autoimmune diabetes
- You are being investigated for latent autoimmune diabetes in adults (LADA)
Early testing may help provide clarity and support timely medical assessment.
What This Test Includes:
IA2 antibodies may support identification of autoimmune activity affecting insulin-producing pancreatic cells.
IAA testing detects antibodies directed against insulin and may be useful in autoimmune diabetes assessment.
ZnT8 antibodies are additional autoimmune markers that may improve detection of type 1 diabetes-related autoimmunity.
