Correction of Positive Bias of the Roche Tina-quant II Hemoglobin A1c (HbA1c) Assay at Low HbA1c Percentages

Correlation between hemoglobin A1c (HbA1c) and average blood glucose: can HbA1c be reported as estimated blood glucose concentration?

Glycation is the nonenzymatic addition of sugar to amino groups of proteins. While virtually any protein in the body can be glycated, for convenience and ease of obtaining a sample, glycated hemoglobin is measured in the blood obtained from a patient. Blood glucose concentrations exhibit wide diurnal fluctuations due to food ingestion, exercise, and other factors. In contrast, the concentration...

A Study Assessing the Association of Glycated Hemoglobin A1C (HbA1C) Associated Variants with HbA1C, Chronic Kidney Disease and Diabetic Retinopathy in Populations of Asian Ancestry

Glycated hemoglobin A1C (HbA1C) level is used as a diagnostic marker for diabetes mellitus and a predictor of diabetes associated complications. Genome-wide association studies have identified genetic variants associated with HbA1C level. Most of these studies have been conducted in populations of European ancestry. Here we report the findings from a meta-analysis of genome-wide association stu...

HbA1c and interference due to hemoglobin disorders

Very low HbA1C, is it a problem?

Dear Editor An important problem to manage diabetes mellitus is controlling the patients` blood glucose. Fluctuation of blood glucose results in molecular biochemistry change and can result in unwanted diabetic complications (1). In clinical practice, hemoglobin A1C (HbA1C) is a common useful laboratory test to follow-up patients with diabetes (2). Sometimes, an unexpecte...

Pitfalls of glycated hemoglobin in the glycemic assessment of diabetes patients with hemoglobin louisville: role of serum fructosamine.

Fasting blood glucose measurements were made using the hexokinase method in a Cobas 6000 (Roche Diagnostics, Rotkreuz, Switzerland). Determinations of HbA1c were performed on ethylenediaminetetraacetic acid–anticoagulated blood sample by two methods: high-performance liquid chromatography (HPLC) (HA-8160 in diabetic mode, A. Menarini Diagnostics, Florence, Italy), which detected no abnormal hem...
