Why we check our blood glucose 2 hours post prandial? can it check less or more hours?

Testing Blood Sugar: Yes. There are all kinds of ways to test for and interpret blood sugar problems. The most common scenario is a three hour test where you get multiple blood sugar testing and then a pattern is plotted from the data.

Standardized time: Two hours after a meal is a standardized time that has been scientifically studied and normal vs. Abnormal levels have been documented. We can compare your results to these normals and see how well you're doing.
