Common Questions

Our Research

Following are answers to our most commonly asked questions about our research. If you don’t see your question here, feel free to contact us.

How long will it take to get my results?

If you live in the U.S., it takes 4-6 weeks to get your screening results. Outside the U.S. it takes a little longer to allow for shipping. TrialNet forwards all samples from screenings and studies to specialized laboratories across the U.S. This way, all samples are processed in a consistent way, meeting strict requirements for scientific research. The process takes a little longer, but it’s an important step in ensuring you receive the most accurate results.

How will I be notified of my results?

If your results are negative, you will receive a letter in the mail. If they are positive, a TrialNet representative will call you to discuss your results and next steps.

If my child tests positive for T1D autoantibodies, will he/she definitely get type 1 diabetes?

If your child is under age 18 and tests positive for one autoantibody, his/her risk of developing T1D is low at this time. But, because chances of developing T1D are highest during childhood and autoantibodies develop faster in growing children, we recommend yearly rescreening until age 18.If your child has two or more autoantibodies, the likelihood of developing T1D nears 100%. Detecting the disease in its earliest stage gives you the opportunity to change the course of the disease. TrialNet offers clinical trials testing ways to slow or stop the disease at every stage. We also provide close monitoring.

Is there a cost for TrialNet screening, monitoring, or studies?

Participants in TrialNet monitoring, prevention and new onset studies receive payment for travel and related expenses. There is no payment for screening.

Will my insurance be notified of my results?

No. Your results are strictly confidential and will be shared only with you and within TrialNet.

Why do my children need to be rescreened until they turn 18?

Chances of developing T1D are highest during childhood years and autoantibodies develop faster in growing children. For these reasons, we recommend yearly rescreening until age 18.

What is an Oral Glucose Tolerance Test?

An Oral Glucose Tolerance Test (OGTT) is when you drink a sugary drink to show if your body makes enough insulin to cover the amount of glucose you would get in a regular meal. If your body can’t, it may mean that diabetes is starting to develop.

What is a Mixed Meal Tolerance Test?

A Mixed Meal Tolerance Test (MMTT) tests how much insulin your body is still making. It involves drinking 'BOOST’ that tastes like a milkshake, and contains a mixture of protein, fat and carbohydrates. The drink raises your blood sugar, causing insulin to be released from your beta cells. TrialNet Coordinators will take blood samples periodically during this test.
