Is it true or false that the confirmation of gestational diabetes mellitus (GDM) occurs after 3 hours if blood sugar is greater than 130-140 mg/dl?

• A. True
• B. False
• C. Depends on the individual case
• D. Only in specific populations

Answer: (A)

The statement is true because the confirmation of gestational diabetes mellitus (GDM) typically involves an oral glucose tolerance test (OGTT) after a screening test that indicates elevated blood sugar levels. While various thresholds can be used, a blood sugar level greater than 130-140 mg/dl during the screening indicates a need for further testing.

After this initial screening, a standard protocol is often followed which includes measuring blood sugar levels at fasting and then at intervals after consuming a glucose solution. If the blood sugar levels exceed the specified criteria, such as being above 130-140 mg/dl after three hours in the OGTT, this confirms a diagnosis of GDM. This aligns with current guidelines that classify the condition based on these values.

Considering the context, other options like whether the confirmation depends on the individual case or specific populations would suggest that there might be variations in testing protocols or thresholds; however, the standard for the confirmation of GDM is well established in clinical practice.
