BeAM value (bedtime-to-morning glucose difference)
Difference between bedtime and morning glucose to gauge unmet postprandial control on basal insulin.
BeAM value (bedtime-to-morning glucose difference)
Bedtime glucose

When to use
- Adults with type 2 diabetes on optimised/titrated basal insulin with persistent hyperglycemia, to decide whether to target postprandial glucose.
Formula
BeAM value = bedtime blood glucose - morning (fasting) blood glucose (mg/dL).
Pearls and pitfalls
- Described from pooled phase 3 basal-insulin trial data; not a formally validated single cut-off, but larger positive values track with a greater postprandial contribution.
- A negative BeAM value has been proposed as a relative contraindication to intensifying prandial insulin.
