If test results are normal, repeat testing should be performed at least every three years. CTFPHC 33 There is fair evidence to recommend screening patients with hypertension or hyperlipidemia for type 2 diabetes to reduce the incidence of CV events and CV mortality.

Current evidence is insufficient to assess balance of benefits and harms of routine screening for type 2 diabetes in asymptomatic, normotensive patients. Gestational diabetes AACE 32 In all pregnant women, fasting glucose should be measured at the first prenatal visit no later than 20 weeks' gestation.

A g OGTT should be performed if the fasting glucose concentration is greater than 85 mg per dL 4. Women at low-risk may be excluded from glucose testing. Low-risk criteria include age younger than 25 years, BMI of 25 kg per m 2 or less, no history of abnormal OGTT result, no history of adverse obstetric outcomes usually associated with gestational diabetes, no first-degree relative with diabetes, not a member of a high-risk ethnic group.

Women with gestational diabetes should be screened six to 12 weeks postpartum and should receive subsequent screening for the development of diabetes. Women with clinical characteristics consistent with a high risk of gestational diabetes e. If glucose test results are negative, retesting should be performed at 24 to 28 weeks' gestation.

Testing may be excluded in low-risk women see ACOG criteria above. All other women should receive Glucola test or OGTT at 24 to 28 weeks' gestation.

If your doctor thinks you have type 1 diabetes, your blood may also tested for autoantibodies substances that indicate your body is attacking itself that are often present in type 1 diabetes but not in type 2 diabetes.

You may have your urine tested for ketones produced when your body burns fat for energy , which also indicate type 1 diabetes instead of type 2 diabetes.

Gestational diabetes is diagnosed using blood tests. If your risk is higher for getting gestational diabetes due to having more risk factors , your doctor may test you earlier. Results can differ depending on the size of the glucose drink and how often your blood sugar is tested. Ask your doctor what your test results mean.

If your test results show you have prediabetes, ask your doctor or nurse if the lifestyle change program offered through the CDC-led National Diabetes Prevention Program is available in your community.
