(collected the day of the consult or within 90 days prior) was 8.0%, and at least one subsequent A1C, performed after 3 months, was measured. A third A1C was collected in patients who had been seen for 6 months at the time of data collection. The mean SD A1C was calculated for each of the three time points, and a t test was performed to determine statistical significance between levels. A total...

We aimed to estimate the cutoff value of glycated hemoglobin (HbA1c, A1c) for fasting plasma glucose (FPG) of 126 mg/dL in the Korean adult population, using the 2011 Korea National Health and Nutrition Examination Survey. A total of 5,421 participants without a history of diabetes and over 19 years of age were included in the analysis. A point-wise area under the receiver operating characteris...

Hemoglobin A1c (Hb A1c) 2 is the analyte most commonly measured in clinical laboratories for patients with diabetes mellitus. Physicians use Hb A1c to monitor long-term glycemic control, adjust therapy, and predict complications of diabetes. Recently, Hb A1c was added as a criterion for the diagnosis of diabetes. Unlike most analytes, many patients with diabetes know their Hb A1c value and are ...

OBJECTIVE Hemoglobin A1c (A1C) has recently been recommended for diagnosing diabetes mellitus and diabetes risk (prediabetes). Its performance compared with fasting plasma glucose (FPG) and 2-h post-glucose load (2HPG) is not well delineated. We compared the performance of A1C with that of FPG and 2HPG in preoperative cardiac surgery patients. METHODS Data from 92 patients without a history o...

BACKGROUND Little is known about the relative contribution of long-term glycemic variability to the risk of macrovascular complications in type 2 diabetes. This study was conducted to evaluate the effect of A1C variability on the progression of carotid artery intima-media thickness (IMT) in type 2 diabetic patients. METHODS Among type 2 diabetic patients who visited Hallym University Sacred H...

OBJECTIVES The purpose of this study was to determine any correlation between frequency of self-monitoring of blood glucose (SMBG), frequency of patient-provider communication of SMBG (reporting), and hemoglobin A1C for patients with non-insulin-dependent diabetes solely on oral medications. RESEARCH DESIGN AND METHODS 191 charts of patients with type 2 diabetes treated solely with oral hypog...

A reduction of A1C levels during pregnancy in women without diabetes has been reported (1–6), suggesting that the goal for A1C during pregnancy complicated with diabetes should be lowered. The decrease in fasting blood glucose levels during the first trimester of normal pregnancy (7,8) may explain the lower A1C levels found in early pregnancy (1,2,3,5). A further decrease of A1C in late pregnan...

OBJECTIVES We examined the association between glycemic control determined by preprocedural hemoglobin A1c (A1c) and the incidence of target vessel revascularization (TVR) in diabetic patients undergoing elective percutaneous coronary intervention (PCI). BACKGROUND Patients with diabetes mellitus (DM) have increased rates of restenosis and a worse clinical outcome after PCI than patients with...

OBJECTIVE To evaluate two alternatives to the fasting plasma glucose (FPG) test for diabetes screening in Latin America. METHODS Eight hundred adults without diabetes were recruited in a primary care clinic in Honduras. An equation-based screening formula, incorporating a random capillary glucose test and other risk factors, was used for initial screening. All patients with a screening-based ...
