When a person’s blood sugar levels are slightly higher than normal, doctors might suspect they have diabetes, but it would be unclear. We often use the term “gray areas” in these situations because the diagnosis is not confirmatory.
This is where the glucose tolerance test becomes incredibly important. It can complement the usual tests like fasting, post-meal blood sugar, and HbA1C, providing additional information when needed.
