Result
Meets the criteria for gestational diabetes (GDM)
Raised values
1 of 1 (1 is enough)
Standard
India — DIPSI / MoHFW (75 g, non-fasting, 2-hour)
What happens next
Diet and activity advice, home glucose monitoring (targets usually fasting < 95 mg/dL and 1-hour < 140 or 2-hour < 120), and medicine if targets are not met
Your doctor makes the diagnosis — labs and countries use different tests and cut-offs. GDM usually goes after birth, but a check 6–12 weeks after delivery and every 1–3 years afterwards is advised because type 2 diabetes risk is higher.

📘 About the GDM Test
Gestational diabetes (GDM) is diagnosed with a glucose tolerance test, usually at 24–28 weeks (earlier in India, at the first visit). Different countries use different tests and cut-offs — enter your results and choose the test you had.
India's DIPSI test (Ministry of Health) is a single 2-hour reading after 75 g of glucose, fasting or not: 140 mg/dL or more is GDM. WHO's 75 g test uses fasting 92, 1-hour 180 and 2-hour 153 mg/dL — any one value is enough. In the US a 50 g screen is followed by a 100 g 3-hour test where two raised values are needed.

Try this example →💡 Cut-offs at a glance (mg/dL)
- India DIPSI (75 g, 2-hour): ≥ 140
- WHO 2013 / IADPSG (75 g): fasting ≥ 92, 1-hour ≥ 180, 2-hour ≥ 153 — any one
- UK NICE (75 g): fasting ≥ 5.6 mmol/L (101) or 2-hour ≥ 7.8 mmol/L (140)
- US 50 g screen: ≥ 130–140 → 3-hour test
- US 100 g 3-hour (Carpenter–Coustan): 95 / 180 / 155 / 140 — two or more
❓ Frequently asked questions
What is a normal GTT result in pregnancy?
On the WHO 75 g test: fasting below 92, 1-hour below 180 and 2-hour below 153 mg/dL. On India's DIPSI test: 2-hour below 140 mg/dL.
Is 140 after 2 hours gestational diabetes?
Yes on the DIPSI test used in India (140 or more). On the WHO test the 2-hour cut-off is 153.
How do I convert mmol/L to mg/dL?
Multiply by 18: 7.8 mmol/L ≈ 140 mg/dL.
Will gestational diabetes go away after birth?
Usually yes, but you should have a glucose test 6–12 weeks after birth and regularly afterwards.
