Final answer:
Routine screening for Gestational Diabetes Mellitus (GDM) is recommended between 24 and 28 weeks of pregnancy to manage risks for both mother and fetus.
Step-by-step explanation:
The recommended gestational age for routine Gestational Diabetes Mellitus (GDM) screening is typically between 24 and 28 weeks of pregnancy. This screening is important because GDM can pose risks to both the mother and fetus, such as the increased likelihood of high birth weight, premature delivery, and the development of type 2 diabetes later in life. Routine screening helps in the early identification and management of GDM to minimize these risks.
During the screening, a glucose challenge test (GCT) is typically performed. This involves drinking a sugary solution and having blood drawn to measure blood glucose levels. If the initial GCT results are elevated, further testing with an oral glucose tolerance test (OGTT) may be done to confirm the diagnosis of GDM.
