Serum fructosamine and glycated haemoglobin (HbA1) were measured in capillary samples from diabetic children and compared with samples from non-diabetic children. Glycaemic control was assessed clinically and by average daily glucose values recorded by home monitoring. Fructosamine correlated with HbA1 and with average glucose values measured over 30 days. HbA1 also correlated with average gluc...

OBJECTIVE Haemoglobin A1c (Hb A1c) is routinely used for monitoring glycemic control in patients with diabetes. Hb A1c seasonal fluctuations can be directly related to different biological, geographical and cultural influences. Our purpose was to evaluate seasonal variation of Hb A1c in a hospital-based adult population over a period of 5 years. MATERIALS AND METHODS We analyzed retrospective...

Concentrations of total glycosylated haemoglobins (Hb A1) were measured in 40 diabetics at diagnosis and at monthly intervals after treatment with chlorpropamide, insulin, or diet alone was begun. The mean Hb A1 concentration at presentation in 16 patients treated with chlorpropamide was significantly higher than that in 12 patients treated with insulin, and the duration of glycaemic symptoms w...

CLINICAL QUESTION In the monitoring of patients with type 1 and type 2 diabetes, what advantages does point-of-care HbA(1c) testing provide over current practice?

OBJECTIVE Examine clinical indicators to evaluate diabetes care in Mexico. MATERIAL AND METHODS Diabetics (self reported, with therapy) were examined with standardized questionnaires, anthropometry, glucose, lipids and glycohemoglobin. Data were analyzed statistically. RESULTS There were 2 644 patients, 677 cases without access to medical care (73% women), most lived in rural communities an...

Hemoglobin A1c (HbA1c) measurements are important for monitoring glycemic control in patients with diabetes. The positive impact of point-of-care HbA1c measurements on patient management is described in the literature. The general analytical requirements for HbA1c testing are described. The analytical evaluation of a new point-of-care HbA1c analyzer, suitable for a physician's office, against t...

We evaluated a colorimetric assay for glycosylated hemoglobin to determine the effects of several variables --oxalic acid concentration, extraneous glucose, hemoglobin concentration, hydrolysis interval, and 5-hydroxymethylfurfural destruction--and the precision. The interference seen when the blood glucose concentration exceeds 2.0 g/L (11 mmol/L) can be eliminated by washing the erythrocytes ...

Study selection and assessment: randomised controlled trials (RCTs) that were published from 1990–2000 in English, evaluated educational interventions in adult outpatients with diabetes, and reported on glycated haemoglobin (HbA1c) concentrations before and after the intervention and at >12 weeks after the intervention. An educational intervention was defined as any non-pharmacological educatio...
