Corrected Fructosamine improves both correlation with HbA1C and diagnostic performance

Association of Glycated Proteins with Inflammatory Proteins and Periodontal Disease Parameters

“…There are no studies exploring this correlation specifically in periodontitis patients with or without diabetes; however, a recent study explored this relation in over 20,000 subjects suffering from type 1 or 2 diabetes, prediabetes, or no diabetes. They reported a correlation coefficient of 0.78 in all subjects [22]. The disparity might be due to a much smaller sample size with only 22% type 2 diabetes patients in our study.…”

Low fructosamine and mortality – A long term follow-up of 215,011 non-diabetic subjects in the Swedish AMORIS study

“…Nonetheless, in reasonable intervals of each marker (99.8 % of all subjects) a positive linearity prevailed. Serum albumin, which has burdened the potential use of fructosamine, 3,[125][126][127] was rather uncorrelated with fructosamine in the hyperglycemic interval.…”

The use of fructosamine in cystic fibrosis-related diabetes (CFRD) screening

“…1A, r 2 = 0.2389, p = 0.029). While controversial, some have advocated for the need to normalize serum fructosamine results to the total protein concentration [14]. Given that poor nutritional status and malabsorption are common in the CF population, a reduction in the total protein level could affect fructosamine concentration in a manner that is independent of glycemic control.…”
