Type 1 Family Members Screening
Why Screen Family Members for Type 1 Diabetes?
Relatives of people with Type 1 diabetes have a 10 to 15 times greater risk for the disease than people with no family history. We don’t yet know the genes that cause diabetes. However, we can detect antibodies that attack the insulin-producing beta cells months or years before diabetes develops. The goal of the TrialNet Natural History Study is to identify family members who are most at risk and to prevent the process from progressing to diabetes.
Who is most at risk to develop Type 1 Diabetes?
The closer the blood relationship, the greater one’s risk of developing T1D. For example, identical twins have a higher risk than full siblings.
Relative with Diabetes Risk of Developing Type 1 DM
Identical Twin 1 in 2
Brother/Sister 1 in 20
No Family History 1 in 250

What does screening entail?
With a single blood tube drawn from a vein in the arm, four different auto-antibodies can be tested to predict one’s risk of developing T1D.
What if I’m not sure if my relative has type 1 or type 2 diabetes? For the purposes of this study, type 1 diabetes is defined as developing diabetes before age 40 years and starting on insulin injections within a year of diagnosis.
What are my options if I/my child is at risk to develop T1D?
There is no proven way to prevent diabetes, but the Oral Insulin Trial aims to test whether ingesting a capsule of insulin by mouth every day will prevent or delay the development of T1D.
What are my options if I/my child have already developed T1D?
New Onset Studies are being conducted for those diagnosed within the past three months.
