BACKGROUND The present study is designed to evaluate the validity of the measurement of capillary blood hemoglobin A1c levels in comparison with venous blood hemoglobin A1c. METHODS The data of this cross-sectional study are collected from a sample of 45 Iranian diabetic patients referred to one particular laboratory for the assessment of HbA1c level during a period from April to December 201...

BACKGROUND The increasing prevalence of diabetes in Ontario means that there will be growing demand for hemoglobin A1c (HbA1c) testing to monitor glycemic control for the management of this chronic disease. Testing HbA1c where patients receive their diabetes care may improve system efficiency if the results from point-of-care HbA1c testing are comparable to those from laboratory HbA1c measureme...

background the use of glycemic thresholds for diabetes diagnosis is controversial. however, no information is available regarding glycemic and glycated hemoglobin (hba1c) thresholds for detecting diabetic retinopathy (dr) in the iranian population. objectives the main purpose of the current investigation was to examine the association of fasting plasma glucose (fpg) and hba1c levels with diabet...

• The hemoglobin A1c (HbA1c) test is a marker for average blood glucose levels in the months prior to testing and is the favored measure of glycemic control for patients with diabetes. The American Diabetes Association recommends HbA1c testing every 3-4 months for Type II diabetes patients who use insulin or with results outside the HbA1c recommended range. • Individuals with HbA1c values in ex...

OBJECTIVE To assess the influence of smoking on glycated albumin (GA) to hemoglobin A1c (HbA1c) ratio among type 1 diabetes mellitus (T1DM) patients. SUBJECTS AND METHODS Eighty-one T1DM patients (49 females, 32 males, mean age 48 +/- 18 years) were recruited, and data concerning GA/HbA1c ratio and smoking were collected. RESULTS The median levels of GA and HbA1c were 23.3 and 7.4%, respect...

Glycated hemoglobin A1c (HbA1c) is routinely used in the diagnosis of diabetes mellitus (DM) and for monitoring the long-term glycemic control in patients already diagnosed with DM. HbA1c is measured in the clinical laboratory based either on the charge of the glycated molecule by cation exchange high performance liquid chromatography (CE-HPLC) or electrophoresis, or on the physical structure o...

Hemoglobin A1c (HbA1c) is widely used as an index of mean glycemia, a measure of risk for the development of diabetes complications, and a measure of the quality of diabetes care. Emerging literature suggests that, although HbA1c levels change little over time within persons without diabetes, they vary considerably among individuals, suggesting that factors other than glycemia may impact HbA1c....

G lycated hemoglobin concentrations (most commonly hemoglobin A1C; HbA1c) reflect time-averaged blood glucose during the previous 2–3 months and are used as the gold standard for longterm follow-up of glycemic control. Standardization with common calibration was first proposed in 1984 (1). It was only after the publication of the Diabetes Control and Complications Trial (DCCT) study in 1993 (2)...

To examine the impact of hemoglobin A1c (HbA1c) criterion on the diagnosis of prediabetes in Koreans, we analyzed nationally representative cross-sectional data of 5,845 Korean adults aged ≥20 years from the Fifth Korea National Health and Nutrition Examination Survey 2011. Standardized prevalence rates of prediabetes in Korean adults by fasting plasma glucose (FPG; 5.6-6.9 mmol/L), HbA1c (5.7-...

INTRODUCTION Abnormal glucose metabolism is an independent risk factor for poor outcome following acute ischemic stroke. However, the relationship between initial hemoglobin A1c level and functional outcome (defined by modified Rankin Scale scores) following small-artery occlusion, a subtype of ischemic stroke, is unknown. The aim of the present study was to evaluate this association among pati...
