Use of A1c POCT offers additional utility; immediate A1c values help verify the accuracy of the self-monitoring of blood glucose (SMBG) results that patients present in the clinic. This is particularly important when patients do not bring their log books or meters into the clinic. The availability of immediate A1c testing allows clinicians to expedite results to patients and readily change trea...

RESULTSdThe association between A1c and mortality was U-shaped. Compared with an A1c of 7–7.9%, the hazard ratios (95%CI) for A1c levels were 1.35 (1.09–1.67) for,5%, 1.18 (1.01– 1.37) for 5–5.9%, 1.21 (1.05–1.41) for 6–6.9%, 1.16 (0.94–1.43) for 8–8.9%, and 1.38 (1.11– 1.71) for$9.0%, after adjustment for age, sex, race, BMI, serum albumin, years of dialysis, serum creatinine, 12 comorbid cond...

OBJECTIVE To characterize the cardiovascular risk profile of subjects categorized differently by A1C- and oral glucose tolerance test (OGTT)-based diagnostic criteria for diabetes according to the recommendations of the American Diabetes Association (ADA). RESEARCH DESIGN AND METHODS An OGTT, A1C, and several cardiovascular risk factors were assessed in 964 individuals without known diabetes ...

OBJECTIVE To determine the individual persistence of the relationship between mean sensor glucose (MG) concentrations and hemoglobin A(1c) (A1C) from the Juvenile Diabetes Research Foundation Continuous Glucose Monitoring (CGM) Randomized Trial. RESEARCH DESIGN AND METHODS MG was calculated using CGM data for 3 months before A1C measurements at 3, 6, 9, and 12 months for the CGM group and at ...

OBJECTIVE To identify factors in patients with type 2 diabetes and A1C >7.0% associated with attainment of A1C ≤ 7.0%. RESEARCH DESIGN AND METHODS We used a prospective registry of 5,280 Canadian patients in primary care settings enrolled in a 12-month glycemic pharmacotherapy optimization strategy based on national guidelines. RESULTS At close out, median A1C was 7.1% (vs. 7.8% at baseline...

OBJECTIVE To determine the concurrent, prospective, and time-concordant relationships among major depressive disorder (MDD), depressive symptoms, and diabetes distress with glycemic control. RESEARCH DESIGN AND METHODS In a noninterventional study, we assessed 506 type 2 diabetic patients for MDD (Composite International Diagnostic Interview), for depressive symptoms (Center for Epidemiologic...

We evaluated three newly introduced systems for automated determinations of hemoglobin (Hb) A1c, which allow the processing of large amounts of samples in a routine clinical laboratory. We compared these methods--the Variant HPLC, the Hi-Auto A1c analyzer system, and the Roche immunoassay--with the Diamat HPLC system. All showed good precision and good concordance with the Diamat HPLC. The refe...

OBJECTIVE Abnormal glucose tolerance is rising in sub-Saharan Africa. Hemoglobin A1c by itself and in combination with fasting plasma glucose (FPG) is used to diagnose abnormal glucose tolerance. The diagnostic ability of A1C in Africans with heterozygous variant hemoglobin, such as sickle cell trait or hemoglobin C trait, has not been rigorously evaluated. In U.S.-based Africans, we determined...

BACKGROUND There is limited information in the primary literature regarding the relationship of medication adherence to attainment of glycosylated hemoglobin A1c (A1c) goals. The 2 oral antihyperglycemic medications, sulfonylurea and/or metformin, were chosen for retrospective analysis because they are the 2 most common oral medications used by patients with diabetes. OBJECTIVE To describe th...
