[Fructosamine and glycosylated hemoglobin as parameters of hyperglycemia]

We have determined the parameters fructosamine and A1 glycosylated hemoglobin, observing a good correlation between them. When analyzing both techniques, the determination of fructosamine proved to be more precise. Considering the significance of each of the tests, we conclude that these parameters cannot substitute for each other but are complementary and that the convenience of fructose determination can not invalidate the utility of determining the glycosylated hemoglobin.
