Glycated Hemoglobin Fructosamine Comparison
May 19 2019 UncategorizedWhen the best isn’t possible, how low can you go? the biologic variation database, compiled by the spanish cc society and dr. carmen ricos, not only includes desirable and optimal specifications for imprecision, bias and total error, but also minimum specifications. for labs unable to achieve the recommended level of quality, here at least is the floor on performance.. A fasting plasma glucose of ≥7.0 mmol/l, a 2-hour plasma glucose value in a 75 g oral glucose tolerance test of ≥11.1 mmol/l or a glycated hemoglobin (a1c) of ≥6.5% can predict the development of retinopathy. this permits the diagnosis of diabetes to be made on the basis of each of these parameters.. Hemoglobin a. hba 1c is the stable product of nonenzymatic irreversible glycation of the beta chain of hemoglobin by plasma glucose and is formed at rates that increase with increasing plasma glucose levels. hba 1c levels provide an estimate of plasma glucose levels during the preceding 1-3 months. the reference range for nondiabetic people is 6% in most laboratories..
In a similar way to hemoglobin a1c testing (which measures the glycation of hemoglobin), fructosamine testing determines the fraction of total serum proteins that have undergone glycation (the glycated serum proteins). since albumin is the most abundant protein in blood, fructosamine levels typically reflect albumin glycation.. A fasting plasma glucose of ≥7.0 mmol/l, a 2-hour plasma glucose value in a 75 g oral glucose tolerance test of ≥11.1 mmol/l or a glycated hemoglobin (a1c) of ≥6.5% can predict the development of retinopathy. this permits the diagnosis of diabetes to be made on the basis of each of these parameters..

Hemoglobin (haemoglobin bre) (from the greek word αἷμα, haîma ‘blood’ + latin globus ‘ball, sphere’ + -in) (/ ˌ h iː m ə ˈ ɡ l oʊ b ɪ n, ˈ h ɛ m oʊ ˌ-/), abbreviated hb or hgb, is the iron-containing oxygen-transport metalloprotein in red blood cells (erythrocytes) of almost all vertebrates (the exception being the fish family channichthyidae) as well as the tissues of some. Individuals with iron deficiency anemia have increased a1c and fructosamine concentrations , both of which are reduced by therapy with iron (54,55). a mechanism for the higher a1c was recently identified by the demonstration that malondialdehyde, which is increased in subjects with iron deficiency anemia , augments glycation of hemoglobin. Hemoglobin a. hba 1c is the stable product of nonenzymatic irreversible glycation of the beta chain of hemoglobin by plasma glucose and is formed at rates that increase with increasing plasma glucose levels. hba 1c levels provide an estimate of plasma glucose levels during the preceding 1-3 months. the reference range for nondiabetic people is 6% in most laboratories..
