Why Get Tested
- Early Detection: Identifying diabetes early can help you manage it better and reduce the risk of complications.
- Prevention: If you’re at risk, testing can help catch prediabetes, allowing you to make lifestyle changes to prevent full-blown diabetes.
- Management: If you’re already diagnosed, regular testing helps track your blood sugar levels and adjust treatment as needed.
When to Get Tested
- Routine Screening:
Adults: If you’re over 45, it’s a good idea to get tested every 3 years, especially if you’re overweight or have other risk factors.
Younger Adults: If you’re under 45 but have risk factors like obesity, a sedentary lifestyle, or a family history of diabetes, you might need testing earlier.
- Pregnant Women:
Early Screening: If you’re at high risk for gestational diabetes (e.g., you’re overweight, have a family history, or had it in a previous pregnancy), you might be tested earlier.
Routine Screening: Typically, gestational diabetes screening is done between 24 and 28 weeks of pregnancy.
- Symptoms:
If you have symptoms like excessive thirst, frequent urination, extreme fatigue, or blurred vision, get tested right away.
Types of Tests
- Fasting Blood Sugar Test:
What It Is: Measures blood sugar after an overnight fast.
Normal Level: Less than 100 mg/dL.
Prediabetes: 100-125 mg/dL.
Diabetes: 126 mg/dL or higher.
- Oral Glucose Tolerance Test (OGTT):
What It Is: Measures blood sugar before and 2 hours after drinking a sugary solution.
Normal Level: Less than 140 mg/dL after 2 hours.
Prediabetes: 140-199 mg/dL after 2 hours
Diabetes is indicated by a blood sugar of 200 mg/dL or more two hours after a glucose test.
- Hemoglobin A1c Test:
What It Is: Reflects average blood sugar levels over the past 2-3 months.
Normal Level: Less than 5.7%.
Prediabetes: 5.7% to 6.4%.
Diabetes: 6.5% or higher.
- Random Blood Sugar Test:
What It Is: Measures blood sugar at any time, regardless of when you last ate.
Diabetes: 200 mg/dL or higher, along with symptoms.
Tests for Gestational Diabetes
- Initial Screening:
Glucose Challenge Test: A preliminary test where you drink a sugary liquid, and your blood is tested after 1 hour. If the result is high, further testing is needed.
- Confirmatory Testing:
Oral Glucose Tolerance Test (OGTT): If the initial screening is abnormal, this test measures blood sugar at fasting and then at intervals after consuming a sugary drink
After a Diagnosis
- Follow-Up:
Regular Monitoring: Depending on your diagnosis, you’ll need regular tests to monitor your blood sugar levels.
-
- Lifestyle Changes: Adjustments in diet, exercise, and sometimes medication will be recommended.
- Education and Support:
Diabetes Management: You’ll get advice on managing diabetes, including monitoring blood sugar, understanding your medication, and making lifestyle changes
