Most people with diabetes are familiar with the A1c test as a measure of cumulative exposure to glucose over a period of three months.
Recently researchers looked into whether an elevated A1c predicted the development of type 2 diabetes in healthy women. In a study published in the American Journal of Medicine, they examined 26,563 women, of whom 1,238 developed type 2 diabetes over a ten-year period.
They found that A1c was a strong predictor of type 2 diabetes, the risk for which rose right along with rising A1c’s.
