Blood Glucose (After 2 Hours/75g Glucose) Test

The Blood Glucose (After 2 Hours/75g Glucose) Test is part of the Oral Glucose Tolerance Test (OGTT) and measures blood sugar levels two hours after consuming 75g of glucose. It is used to diagnose diabetes, prediabetes, and gestational diabetes.

Why is the Blood Glucose (2 Hour/75g) Test Important?

• High blood sugar levels after 2 hours may indicate diabetes, impaired glucose tolerance (prediabetes), or gestational diabetes.
• This test helps assess how well the body processes glucose and is more accurate than a fasting blood sugar test alone.
• It is recommended by the American Diabetes Association (ADA) for diabetes screening.

When is the Test Recommended?

• If a person has symptoms of excessive thirst, frequent urination, unexplained weight loss, or fatigue.
• For pregnant women (gestational diabetes screening) between 24-28 weeks of pregnancy.
• For individuals with risk factors like obesity, family history of diabetes, or metabolic syndrome.
