What is the normal level for an Oral Glucose Tolerance Test (OGTT)?

• A. Less than 120 mg/dl
• B. Less than 140 mg/dl
• C. Less than 160 mg/dl
• D. Less than 180 mg/dl

Answer: (B)

The normal level for an Oral Glucose Tolerance Test (OGTT) is indeed defined as less than 140 mg/dl. This test is used to evaluate how well the body processes glucose and helps in diagnosing conditions like prediabetes and diabetes. When a person undergoes the OGTT, their blood glucose levels are measured prior to ingestion of a glucose solution and then at intervals afterward, usually after two hours. A result less than 140 mg/dl indicates that the body is effectively managing glucose levels, while values equal to or above this threshold suggest potential issues with glucose metabolism. Values less than 120 mg/dl would fall into a different classification, generally indicative of excellent glucose handling, while ranges above 140 mg/dl begin to suggest impaired glucose tolerance or diabetes, depending on the specific cutoffs used. Thus, the threshold of 140 mg/dl is critical in distinguishing between normal glucose response and potential metabolic disorders.
