What is the Likelihood of Developing Type 1 Diabetes If You Test Positive for Autoantibodies?
So, you got screened for autoantibodies. The results came back saying you tested positive for one—or more—autoantibodies. The question now becomes—What is the likelihood of you developing type 1 diabetes?
- First—Take a breath. No matter what comes next, you’ve got this!
- Second—Remember that testing positive for autoantibodies is not a type 1 diabetes diagnosis. It’s additional information about your risk of developing type 1 diabetes, which may be why you chose to get screened.
- Third—Know that whatever your risk of developing type 1 diabetes, there’s a path forward and it starts with information.
What’s My Risk of Developing Type 1 Diabetes If I Tested Positive for Autoantibodies?
Studies show that the risk of developing type 1 diabetes increases with the number of autoantibodies detected in screening tests.
Your risk—and what to do next—is different if you tested positive for one vs. two or more autoantibodies.
What happens if you test positive for one autoantibody?
Testing positive for one autoantibody means you’re at higher risk of developing type 1 diabetes in your lifetime than someone who tested for no autoantibodies.
Your risk, however, is much lower than someone who tested positive for two or more autoantibodies.
- If you tested positive for one autoantibody, you have a 15% chance of developing type 1 diabetes in the next 10 years.
- A positive screening test needs to be confirmed with a second blood test, and your doctor may also test for the other type 1 diabetes autoantibodies.
Even if you’re not at high risk of developing type 1 diabetes, your doctor may follow you more closely. He or she may order more tests to screen you for other autoantibodies.
They may also teach you about the early warning signs and symptoms of type 1 diabetes.
What happens if you test positive for multiple autoantibodies?
Unfortunately, testing positive for two or more autoantibodies means you’re at high risk of developing type 1 diabetes in your lifetime.
If you tested positive for multiple autoantibodies, the chance that you’ll develop type 1 diabetes is:
- 44 percent in the next five years
- 70 percent in the next 10 years
- 84 percent in the next 15 years
- Almost 100 percent in your lifetime
If you tested positive for multiple autoantibodies but don’t have any symptoms, the good news is, you’re in the early stages of type 1 diabetes. Your screening results may help you get diagnosed early and prepare for a diagnosis.
What Are the Three Stages of Type 1 Diabetes?
Let’s look at the three stages of type 1 diabetes in more detail.
In stage 1—People have no symptoms or glucose intolerance, and have normal blood-sugar levels.
In stage 2—People still have no symptoms, but may have low or high blood-sugar levels and slight glucose intolerance.
In stage 3—Also known as clinical diabetes, this is the stage where type 1 diabetes is normally diagnosed.
The American Diabetes Association recommends testing blood-sugar levels to determine your short-term risk of developing stage-3 type 1 diabetes.
Your doctor may start testing your blood-sugar levels and may also:
- Refer you to a specialized center for further evaluation.
- Suggest that you participate in type 1 diabetes research.
- If you’re eligible, this may include taking part in a clinical trial for a treatment that may prevent or delay the development of type 1 diabetes.
- Provide you with type 1 diabetes education—so you can learn to spot the warning signs of type 1 diabetes—or refer you to a Certified Diabetes Care and Education Specialist (CDCES).
Even though testing positive for type 1 diabetes autoantibodies is tough, remember that an early diagnosis—thanks to screening—might help you avoid severe and even life-threatening complications!
How to Cope With a Positive Type 1 Diabetes Autoantibody Test
A positive test for multiple autoantibodies—and the associated high risk of developing type 1 diabetes—can be scary and overwhelming.
Not knowing when you’ll be diagnosed might also keep you on edge.
Educate yourself
Dr. Mark Heyman, a diabetes psychologist and a CDCES who’s been living with type 1 diabetes since 1999. Dr. Heyman suggests reframing this test result from “a ticking time bomb” to “the gift of time to prepare.”
“The best thing people who have recently tested positive for diabetes autoantibodies can do is to educate themselves on what diabetes is and how it is managed,” he says.
To start learning about type 1 diabetes, you can:
- Ask your doctor to refer you to a diabetes-education program recognized by the ADA.
- Locate a CDCES near you.
Dr. Heyman also hosts a type 1 diabetes podcast—LiveFree with T1D. It’s a great place to start getting answers to many of your questions about type 1 diabetes!
Find support from a mental-health professional
Preparing for a type 1 diabetes diagnosis may relieve some of your anxiety, but you may need some extra help to cope with the shock of a positive autoantibody test and what this might mean.
Wondering if therapy might help? Check out this episode of the LiveFree with T1D podcast:
If you’d like to get help from a mental-health provider who has expertise in diabetes care, ask your doctor for a referral or consult the ADA’s Mental Health Directory to find a provider near you.
Find support from the type 1 diabetes community
