1. Screening for diabetes based on FPG, HbA1c, or 2-hour plasma glucose 75-g OGTT is assessed. [Non-randomized controlled trial, general recommendation]

2. Annual screening for diabetes [Expert opinion, general recommendation] should be considered for adults aged ≥35 and adults aged ≥19 who have one or more risk factors (Table 5). [Uncontrolled studies, general recommendation]

3. Additional tests are indicated if FPG or HbA1c levelsmeet any of the following. [Expert opinion, general recommendation]

1) FPG level 100 to 109 mg/dL or HbA1c 5.7% to 6.0%: test FPG or HbA1c levels annually, and consider 75-g OGTT if body mass index (BMI) is ≥23 kg/m2

2) FPG level 110 to 125 mg/dL or HbA1c 6.1% to 6.4%: consider 75-g OGTT

4. Screen individuals with GDM for diabetes at 4 to 12 weeks postpartum, using the 75-g OGTT. [Randomized controlled trial, general recommendation]
