One hundred eleven laboratories, using 21 different methods based on five different principles, determined glycohemoglobin (GHb) percentages in two identical series of six lyophilized hemolysates and three similarly processed calibrators, distributed 3 months apart. To assign GHb percentages to calibrators, we used HbA1c results from nine participants who used the Bio-Rad Diamat high-performanc...

BACKGROUND AND OBJECTIVE The influence of glycemic control on cardiovascular (CV) complications or survival is not clear in diabetic patients with end-stage renal disease (ESRD). Although glycohemoglobin (HbA1c) is widely used as a marker of hyperglycemia in these patients, it may be unreliable because of shortened erythrocyte lifespan. Glycated albumin (GA) is an alternative marker. We investi...

Abstract Background HbA1c testing using EDTA whole blood as specimens is essential for monitoring glycemic control in diabetic patients. In the laboratory that total automation system, transportation process might be impact quality of result according to red cell sedimentation. This study, we aimed evaluate from sediment which happen system. Methods samples (n = 50) were mixed once and levels d...

BACKGROUND Diabetes mellitus is a major health problem worldwide with long-term micro- and macrovascular complications responsible for a majority of its morbidity and mortality. The development and progression of these complications relate strongly to glycemic control. METHODS We reviewed the literature extensively for studies that relate glycemic control to the development and progression of...

BACKGROUND Muscle strength may play an important role in cardiovascular health. The study was intended to evaluate the association between cardiometabolic risk, risk of coronary artery disease and handgrip strength by using the relative handgrip strength. MATERIALS AND METHODS Data of 927 Taiwanese aged 53 years and older (510 men and 417 women) were retrieved from a nationwide representative...

Glycosylated hemoglobin and protein were measured in maternal and cord blood of 24 normal, 19 class A, and ten insulin-treated diabetics using an affinity chromatographic technique. Maternal (intrapartum) glycohemoglobin and glycoprotein levels in the diabetics were not significantly different from those in normal controls, suggesting "tight" metabolic control in these patients. Compared with c...
