The Screening Process
Blood Sample Collection
The screening test requires a small blood sample. If you choose at-home collection, you'll receive detailed instructions and all necessary supplies. The process is quick and minimally invasive.
What Gets Tested
TrialNet screens for five diabetes-related autoantibodies:
- GAD65 (Glutamic Acid Decarboxylase)
- IA-2A (Insulinoma-Associated Antigen-2)
- IAA (Insulin Autoantibodies)
- ZnT8A (Zinc Transporter 8)
- mIAA (micro-Insulin Autoantibodies)
This comprehensive panel provides the most accurate picture of your T1D risk.
Results Timeline
You will receive your screening results in 4-6 weeks. TrialNet will contact you by phone and email with your results and next steps.
Understanding Your Results
No Autoantibodies Detected: Excellent news! You are currently at low risk for developing Type 1 diabetes. However, if you remain eligible, TrialNet may recommend rescreening every 2 years since autoantibodies can develop over time.
One Autoantibody Present: You have an increased risk of developing T1D. TrialNet will invite you to participate in follow-up monitoring every 6 months to track any changes.
Two or More Autoantibodies: You have early-stage Type 1 diabetes. TrialNet will schedule a follow-up visit to determine eligibility for prevention studies aimed at delaying or stopping disease progression.

Benefits of Early Detection
Knowing your T1D status before symptoms appear offers significant advantages:
Avoid DKA: Early diagnosis prevents dangerous diabetic ketoacidosis, which affects about 30% of children diagnosed with T1D without prior screening.
Prepared Transition: If T1D develops, you and your healthcare team can plan for a smooth transition to insulin therapy and diabetes management.
Research Participation: Access to prevention studies that could change the course of the disease.
Family Planning: Understanding your family's risk profile helps with health planning and screening for other relatives.
