Oral Glucose Tolerance Test - 2 Samples (FBS + 2 Hours Post Glucose Load)
The OGTT-2 is a test that measures the body's ability to handle glucose. It involves two blood samples: one taken after fasting (FBS) and the second taken 2 hours after consuming a 75g glucose solution. This test helps diagnose diabetes or pre-diabetes. Note : Arogga will provide 75 gm glucose (charge applicable)

How our test process works!
Overview
- The OGTT-2 measures blood glucose levels at two key points:
- Fasting Blood Sugar (FBS): The glucose level after fasting overnight (usually 8–12 hours).
- 2 Hours Post Glucose Load: The glucose level measured exactly 2 hours after ingesting a glucose solution containing 75 grams of glucose.
Risk Assessment
The test helps in identifying:
- Diabetes mellitus: An inability to effectively manage blood sugar levels.
- Impaired fasting glucose (IFG): Higher-than-normal fasting blood sugar levels, but not high enough to be classified as diabetes.
- Impaired glucose tolerance (IGT): Blood sugar levels that are higher than normal but not in the diabetic range, as indicated by the 2-hour post-load value.
People at risk of glucose metabolism disorders (e.g., obesity, hypertension, family history of diabetes) might undergo this test for early detection.
Normal Range
- Fasting Blood Sugar (FBS): <100 mg/dL (5.6 mmol/L)
- 2 Hours Post-Glucose Load: <140 mg/dL (7.8 mmol/L).
Interpretation of Results
- Fasting Blood Sugar (FBS):
- Normal: <100 mg/dL (5.6 mmol/L)
- Impaired fasting glucose (IFG): 100–125 mg/dL (5.6–6.9 mmol/L)
- Diabetes: ≥126 mg/dL (7.0 mmol/L)
- 2-Hour Post-Glucose Load:
- Normal: <140 mg/dL (7.8 mmol/L)
- Impaired glucose tolerance (IGT): 140–199 mg/dL (7.8–11.0 mmol/L)
- Diabetes: ≥200 mg/dL (11.1 mmol/L).
Sample Type
The test requires a blood sample. The first sample is drawn after fasting (FBS), and the second sample is taken exactly 2 hours after consuming a glucose solution.
