What do my screening results mean?

The stages of T1D are related to the number of autoantibodies present combined with blood glucose levels. These stages can take months or years to develop.

Here are the three stages of T1D:

Stage 1

Two or more autoantibodies are present, but the person has no symptoms and blood sugar levels are normal.

Stage 2

Two or more autoantibodies are present and blood sugars are abnormal, but there are no other symptoms of T1D.

Stage 3

Symptoms have developed, blood sugar levels are persistently high, and the need for insulin therapy is immediately necessary.

Spotting the earliest stages of T1D is so important.

Preventing diabetic ketoacidosis (DKA) protects brain health and saves lives.

Diagnosing T1D before blood glucose levels rise and insulin production plummets — leading to diabetes ketoacidosis — can have tremendous benefits.

DKA is a potentially life-threatening condition, which people often experience at the time they are diagnosed with diabetes. Research has also found that DKA at diagnosis can permanently injure the brain.

Detecting T1D early and monitoring autoantibodies over time means preventing DKA.

What to do next:

If you screen negative for autoantibodies:

If your screening results are negative, you may consider screening again in the future.

If you screen positive for autoantibodies:

If your screening results are positive, it’s important to take action.

  1. Follow up with your healthcare provider for additional testing to confirm your results.
  2. Talk with your healthcare provider about your options and make a plan for further monitoring.
  3. Take advantage of resources from TrialNet and Ask the Experts.
