Analysis

✅ After drinking sugar (1-3 hours), very low tolerances (± 1-3%)

⚠️ The fasting range is quite high.

Maybe it's just the first time!? (The answer from the company says the value may not be stable for the first 24-48 hours)

Accuracy summary:

For after-food trends, it works well.

2️⃣ GDM Mode (Gestational Diabetes Mode)

Ottai has a specific mode for mothers with gestational diabetes (GDM), which is considered very hallmark.

🎯 Target value in GDM Mode

Fasting < 95 mg / dL

1 hour after meal < 140 mg / dL

2 hours after meal < 120 mg / dL

(It is the standard value used in antenatal clinics)

Comment to GDM Mode

🔹 set an alert based on a particular GDM criterion.

🔹 worth 1 hr / 2 hr after a clear meal.

🔹 tell time to peak each meal.
