If you have a relative with Type 1 diabetes, you are 15 times more likely to develop Type 1 diabetes than the general population. By joining us on the Pathway to Prevention study, relatives may be eligible to join one of three important prevention trials. The first step is screening relatives for risk markers called autoantibodies.

By getting screened, you may:

  • Enter a prevention trial
  • Avoid hospitalization
  • Help researchers to closely monitor disease progression.

Who is eligible?

Anyone between the ages of 1 and 45 years with a sibling, child or parent with type 1 diabetes.

Anyone between the ages of 1 and 20 with a sibling, child, parent, cousin, uncle, aunt, niece, nephew, grandparent or half-sibling with type 1 diabetes.

Screening just got easier!

How Does Screening Work?

  • Step 1: First we will ask some eligibility questions.
  • Steps 2-3: We will verify we have your permission to screen your blood sample and collect personal information.
  • Step 4: The Online Screening will ask for some basic family history information and a mailing address.
  • Step 5: We will mail you a screening kit. Take your screening kit to your local Quest for your blood test.
  • Step 6: If your test is negative, we'll send you a letter in 4-6 weeks. If your test is positive, we will call you to discuss your options. Learn More >

Note: Screening at Quest facilities is only available for persons located in the US, If you are located outside of this area, but still want to participate, please click here for more information.
