More U.S. children and adults can benefit from earlier diabetes screening
Diabetes can develop quietly, and prediabetes is common enough that many people may be at risk without realizing it. New CDC guidance also emphasizes earlier type 1 diabetes screening for some people with higher risk, including children.
Many people think diabetes screening starts only after clear symptoms appear. In practice, some U.S. children and adults may benefit from learning their risk earlier, before blood sugar problems turn into an emergency.
That matters because diabetes can develop quietly, and prediabetes is common. For some people, screening can uncover a problem early enough to make prevention, monitoring, and treatment easier to plan.
Why screening can help
Type 2 diabetes often develops slowly, and symptoms may be mild or easy to miss at first. The CDC says many people can have it for years before they are diagnosed. Prediabetes is also common, and it raises the chance of later type 2 diabetes if nothing changes.
Type 1 diabetes is different. It can progress quickly and sometimes first shows up as a medical emergency, such as diabetic ketoacidosis. The CDC says type 1 diabetes develops in stages and can be identified before symptoms appear in some higher-risk people.
Type 2 screening: who may need it earlier
Adults are more likely to be screened for type 2 diabetes or prediabetes as they get older, and screening may begin earlier for people with risk factors such as overweight, obesity, a family history of diabetes, or other clinical risks. The exact timing depends on age, risk profile, symptoms, and a clinician’s judgment.
Children and teens may also be screened if they have risk factors. The CDC notes that type 2 diabetes is becoming more common in younger people, so families should not assume it is only an adult condition.
Type 1 screening: a separate question
Screening for type 1 diabetes is not the same as screening for type 2. The CDC says people with a family history of type 1 diabetes, or with certain autoimmune risk factors, may be offered screening even if they feel well. Screening can begin in childhood, and early detection may help people watch for symptoms and reduce the chance of a severe first diagnosis.
The CDC also notes that most people who develop type 1 diabetes do not have a family member with the condition. That is one reason a clinician may talk with families about whether screening makes sense even when no one in the household has type 1 diabetes.
Common blood tests
MedlinePlus says diabetes testing usually relies on blood tests, not urine tests. Common tests include a fasting plasma glucose test, an A1c test, and an oral glucose tolerance test. These tests help screen for diabetes, confirm a diagnosis, or track how well blood sugar is being managed.
For type 1 diabetes screening, the CDC says a blood test can look for diabetes-related autoantibodies, which are markers of the immune process behind type 1 diabetes.
What a prediabetes result can mean
A prediabetes result does not mean diabetes is already present, but it does mean blood sugar is higher than normal and action may be needed. CDC guidance says people with prediabetes may benefit from follow-up testing, weight-related support when appropriate, and a structured prevention program. Lifestyle changes can lower risk for many people, but the right plan depends on the person.
What a positive type 1 screen can mean
If a type 1 screen is positive, the next step is usually follow-up testing and a clinician visit, not self-treatment. The CDC says people with positive results may need blood sugar checks and specialist care. Early identification can give families time to learn warning signs, plan monitoring, and reduce the chance of an emergency diagnosis.
What readers can do now
If you have questions about diabetes screening, ask a primary care clinician whether you or your child should be tested based on age, family history, weight, other health conditions, or symptoms. If you already have symptoms such as frequent urination, unusual thirst, unexplained weight loss, blurry vision, or extreme fatigue, do not wait for a routine screening visit.
Seek urgent care right away for signs that could suggest diabetic ketoacidosis, such as vomiting, deep or rapid breathing, confusion, or severe dehydration. Those symptoms can become life-threatening quickly.
For many families, the main takeaway is simple: diabetes screening is not only about finding disease after it starts. In the right people, it can also help catch risk early enough to act sooner.
