Connected by T1D

Revealing the familial thread of
type 1 diabetes (T1D) by screening
first- and second-degree relatives can help those who are most at risk avoid complications like DKA at clinical onset.1

300K people are at increased risk of clinical T1D2

Familial history is a strong predictor for T1D; focusing on the family of patients with T1D can help identify presymptomatic patients.3,4

Know Who to Identify

Unravel the presymptomatic story behind T1D

Patients' beta cells may be targeted for destruction before a clinical diagnosis of T1D. Recognition of this process and its implications can prepare families for the risks ahead of clinical onset.5,6

Know What's Happening

Screening can reduce DKA at onset by 50%7,8

Early autoantibody screening can identify those most at risk of developing T1D. Increased awareness and early intervention may improve outcomes at presentation and avoid significant consequences such as diabetic ketoacidosis.1

Know the Benefits

Screening can identify T1D patients before clinical onset1

There are various organizations and resources for T1D screening and clinical trials to advance T1D care.
