Question

How is testing for GDM performed if the screening test is done first?

a) 1-hour glucose challenge test (GCT)
b) 2-hour glucose tolerance test (GTT)
c) Fasting plasma glucose
d) Hemoglobin A1c

Answer 1

The 2-hour glucose tolerance test (GTT) is performed after the screening test to confirm the diagnosis of gestational diabetes mellitus (GDM).

Step-by-step explanation:

The screening test for gestational diabetes mellitus (GDM) is typically followed by further testing to confirm the diagnosis. One common method is the 2-hour glucose tolerance test (GTT). This test is performed by giving the patient an oral dose of glucose and then measuring their blood glucose levels at regular intervals over a two-hour period. This test helps to assess the individual's ability to tolerate glucose and can indicate the presence of GDM.
