What it is

An oral glucose tolerance test measures blood glucose before and after a glucose drink over a defined time window.[1,2]

Why it matters

It is a dynamic response measure rather than a single static glucose point.[1,2]

What it affects

  • It connects glucose handling, insulin response context, pregnancy-related testing context, and diabetes evaluation context.[1,2]
  • The shape of response can matter as much as one number.[1,2]

Interpretation traps

  • Protocols differ by indication and setting.[1,2]
  • BioConst does not tell readers whether they should take an OGTT or interpret their results.[1,2]
