OBJECTIVE A1C levels have been shown to be elevated in relation to glycemia in late pregnancy, although the precise mechanisms remain undetermined. We hypothesized that iron deficiency is involved in the A1C increase in late pregnancy. RESEARCH DESIGN AND METHODS In study 1, A1C, serum glycated albumin, erythrocyte indexes, and iron metabolism indexes were determined in 47 nondiabetic pregnan...

OBJECTIVE A1C is widely considered the gold standard for monitoring effective blood glucose levels. Recently, a genome-wide association study reported an association between A1C and rs7072268 within HK1 (encoding hexokinase 1), which catalyzes the first step of glycolysis. HK1 deficiency in erythrocytes (red blood cells [RBCs]) causes severe nonspherocytic hemolytic anemia in both humans and mi...

Complete automation of high-performance liquid chromatography (HPLC) for determination of hemoglobin F (%Hb F) and hemoglobin A1c (%Hb A1c) levels has made this procedure available in many clinical laboratories. However, the physiological changes in %Hb F during pregnancy and the effects of physiological and supraphysiological levels of %Hb A1c on measurement of %Hb F have not been studied exte...

INTRODUCTION In 1999, the National Diabetes Prevention and Control Program at the Centers for Disease Control and Prevention and its 59 Diabetes Prevention and Control Programs adopted five Healthy People 2010 objectives. These objectives aim to improve the rates of preventive care services among people with diabetes and include annual foot examinations, hemoglobin A1c tests, and annual dilated...

BACKGROUND The relative effect of hemoglobin A1c, blood pressure, and low-density lipoprotein-cholesterol (LDL-C) ("ABC" factors) on the prevention of cardiovascular diseases (CVD) among patients with type 2 diabetes mellitus is poorly understood. This study aimed to evaluate the association of key clinical parameters on CVD risk using a multifactorial optimal control approach in Chinese primar...

background: psychological and behavioral domains are important in coping with type ii diabetes. this study was conducted to assess supportive and coping obstacles in living with type ii diabetes among patients who visited hospitals affiliated to tehran university of medical sciences (tums). methods: this was a cross-sectional study with 600 subjects who participated in the study. data collectio...

Hemoglobin A1c (HbA1c) has been accepted as an index of glycemic control since the mid-1970s and is the best marker for diabetic microvascular complications. Clinically, it is now used to assess glycemic control in people with diabetes. Assays are most reliable when certified by the National Hemoglobin Standardization Program but are subject to confounders and effect modifiers, particularly in ...

Abstract Background Numerous laboratory tests are used in the diagnosis and management of patients with diabetes mellitus. The quality scientific evidence supporting use these assays varies substantially. An expert committee compiled evidence-based recommendations for analysis diabetes. overall strength were evaluated. draft consensus evaluated by invited reviewers presented public comment. Sug...

BACKGROUND With increasing use of glucosamine-containing supplements for the treatment of osteoarthritis, there is increasing concern in the medical community about possible toxic effects. The present study was undertaken to determine whether glucosamine supplementation altered hemoglobin A1c concentrations in patients with well-controlled diabetes mellitus. OBJECTIVE To evaluate possible eff...
