Estimation of glycated hemoglobin by 2,6-dimethylphenol: Sulphuric acid conventional method

Estimation of monosaccharides by the orcinol-sulphuric acid reaction.

Fructosamine assay modified for the estimation of glycated hemoglobin.

CLINICAL CHEMISTRY, Vol. 35, No. 3, 1989 497 4#{176}C. For 12 additional patients (group B) the analysis was performed immediately and repeated 10 and 30 days after collection of the samples, which were stored at room temperature in airtight containers. The data were examined by Student’s paired t-test and linear-regression analysis. In neither group did storage conditions significantly influen...

Accuracy of filter paper method for measuring glycated hemoglobin.

BACKGROUND AND OBJECTIVES Glycated hemoglobin (HbA1c) provides an accurate and reliable method to assess the glycemic control in patients with Diabetes. Its measurement is limited by the inconvenience of sample collection that requires venipuncture, sample handling and storage factors. The aim of this study was to assess the feasibility of using a dried capillary blood spot on a filter paper to...

Biological variability of glycated hemoglobin.

BACKGROUND The measurement of glycated hemoglobin (HbA(1c)) has a pivotal role in monitoring glycemic state in diabetic patients. Furthermore, the American Diabetes Association has recently recommended the use of HbA(1c) for diabetes diagnosis, but a clear definition of the clinically allowable measurement error is still lacking. Information on biological variability of the analyte can be used ...

Glycated hemoglobin in fractionated erythrocytes.

Erythrocytes were fractionated, by centrifugation, on the basis of cell density, which is proportional to cell age. Glycated hemoglobin (Hb A1c) in the fractionated cells was measured and compared with the Hb A1c in whole blood and with the fructosamine concentrations in plasma of normal and diabetic subjects. In normal subjects, Hb A1c increased according to the age of the erythrocytes, but hy...
