Categories of increased risk for diabetes:
All of these tests identify people at risk of developing diabetes. For all 3
tests, the risk of diabetes is not the same throughout the range of results.
Risk for developing diabetes is lower in those who fall at or below the lower
limit and is higher in those with results at the upper end of the range.
However, the number of people that these tests identify and their
characteristics vary between the 3 tests. For example, A1c varies by
race/ethnicity independent of blood glucose levels. Research is ongoing to
ascertain the best use of laboratory blood tests to detect people who may have
prediabetes and to improve the understanding of who has prediabetes
