Diabetes: TrialNet T1D Risk Screening Pathway to Prevention

Condition or Therapy:

Type 1 Diabetes


Endocrinology and Diabetes

What is the goal of this study?

The TrialNet "Pathway to Prevention" study screens relatives of people with type 1 diabetes (T1D) to see if they are at risk of developing the disease. This screening can identify the early stages of T1D years before any symptoms appear. It also helps researchers learn more about how T1D develops and plan new studies exploring ways to prevent it.

Who can join the study?

You qualify for free risk screening if you:

  • Are between the ages of 2.5 and 45 years and have a parent, brother/sister, or child with T1D
  • Are between the ages of 2.5 and 20 years and have an aunt/uncle, cousin, grandparent, niece/nephew, or half-brother/sister with T1D
  • Have not been diagnosed with diabetes

What will happen if my child takes part in this study?

Only a small blood sample is needed. TrialNet screening is available by appointment or you can arrange for test kits that can be mailed directly to you anywhere in the US, free of charge:

  • In-home Test Kit: This kit provides everything you need to collect a blood sample (~10 drops) at home using a finger-stick.
  • Lab Test Kit: You can take this kit to any Quest Diagnostics or LabCorp lab for a blood draw.
  • Or, if you don’t have a Quest or LabCorp lab near you, we can help you arrange for a blood draw at a local lab or doctor’s office.

You will receive your screening results in 4-6 weeks. If your results show you are in the early stages of T1D, we will schedule a follow-up visit to see if you are eligible for a prevention study.
