Tests Doctors use to Diagnose Diabetes

There are several tests that doctors use to diagnose diabetes:

1. Fasting Plasma Glucose test (FPG): This test involves taking a blood sample after an overnight fast. If the blood sugar level is between 100 and 125 mg/dL, it indicates prediabetes. If it is above 126 mg/dL on two separate occasions, it indicates diabetes.
2. Oral Glucose Tolerance Test (OGTT): This test involves taking a blood sample after an overnight fast and then drinking a glucose solution. Blood samples are taken at regular intervals over the next two hours. If the blood glucose level is above 200 mg/dL after two hours, it indicates diabetes.
3. Hemoglobin A1C test: This test measures the average blood sugar level over the past two to three months. A result of 6.5% or higher indicates diabetes.
4. Random Plasma Glucose test: This test involves taking a blood sample at any time of the day, regardless of when the person last ate. If the blood sugar level is above 200mg/dL and the person has symptoms of diabetes, it indicates diabetes.
5. Gestational Diabetes: A pregnant woman is given an oral glucose tolerance test between weeks 24 and 28 of her pregnancy. If the blood sugar level is above 140mg/dL, it indicates gestational diabetes.

It is important to note that diagnosing diabetes is a complex and ongoing process that involves regular monitoring of blood sugar levels. When diagnosed ensure to test your Hemoglobin A1C every three (3) months. Use a spread sheet to track your numbers and compare regularly.
