Proactive Screening

Screening can reduce DKA at onset by ≥50%


Diabetic ketoacidosis (DKA) is a serious event, but screening can identify patients who may be at increased risk1

Screening for autoantibodies has been shown to reduce the incidence of DKA at diagnosis of T1D by ≥50%.2,3

Reduce incidence of DKA icon
Patients who were screened experienced an ~8x lower likelihood of DKA at clinical onset of T1D.4
  • ~30% to ~50% of children in the United States experience DKA at the onset of T1D5
  • Children with moderate or severe DKA experience a shorter “honeymoon phase” than children who do not present with DKA6

Metabolic scarring

DKA at onset may cause a “metabolic scar” in patients, which can lead to worse metabolic control in the short and longer term.1

Metabolic and physical consequences of DKA at onset


  • Lower residual beta-cell function7
  • Higher HbA1c for at least 15 years8
  • Rare neurological trauma such as cerebral edema9

Early identification can improve outcomes at clinical onset

Screening can help identify patients who might benefit from enhanced clinical vigilance and education, which can improve management at onset.1,4
