BACKGROUND Iron deficiency anemia is the most common form of anemia in India. Hemoglobin A1c (HbA1c) is used in diabetic patients as an index of glycemic control reflecting glucose levels of the previous 3 months. Like blood sugar levels, HbA1c levels are also affected by the presence of variant hemoglobins, hemolytic anemias, nutritional anemias, uremia, pregnancy, and acute blood loss. Howeve...

BACKGROUND The purpose of the present study was to find the optimal threshold of glycated hemoglobin (HbA1c) for diagnosis of diabetes mellitus in Chinese individuals. METHODS A total of 8 391 subjects (including 2 133 men and 6 258 women) aged 40-90 years with gradable retinal photographs were recruited. The relationship between HbA1c and diabetic retinopathy (DR) was examined. Receiver oper...

BACKGROUND Diabetic patients with concomitant dyslipidemia are often soft targets for cardiovascular disease and deaths. An early intervention to normalize circulating lipids has been shown to reduce cardiovascular morbidity and mortality. Glycosylated hemoglobin (HbA1c) is routinely used as a marker to indicate long-term glycemic control. AIM Our aim was to test whether HbA1c can serve as a ...

BACKGROUND/AIMS Gastroparesis is characterized by delayed gastric emptying without obstruction. Diabetes is frequently associated with poor glycemic control and delayed gastric emptying. Gastric emptying scintigraphy (GES) is the standard for measuring gastric emptying. Serum hemoglobin A1C (HbA1C) measures prolonged glycemic control with normal as < 7% glycated. To date, no correlation of seru...

AIMS In this study, we compared the glucose-lowering effectiveness of insulin analogues and their combination according to baseline glycemic status in patients with type 2 diabetes (T2D) from the A1 chieve(®) study conducted in Korea. METHODS This sub-analysis from the A1 chieve(®) study was a 24-week prospective, multicenter, non-interventional, open-labelled study. Of the 4058 patients, 307...

OBJECTIVES To review the various hemoglobin (Hb) A1c methods, with a focus on interferences resulting from Hb variants. METHODS HbA1c is a marker used for the diagnosis and management of diabetes. Each available HbA1c method has advantages and challenges, such as its susceptibility to interferences. RESULTS The presence of Hb variants and/or abnormalities in RBC turnover cannot only interfe...

Background: The traditional role of HbA1c analysis has been for assessing glycemic control in patients with diabetes. The results of semi-final studies demonstrated that early, intensive glycemic control could significantly reduce the risk of a range of diabetes related complications, and permitted the establishment of precise HbA1c target values for treatment goals. Aim: This study was to dete...
