Interpretation of hemoglobin A1C in primary care setting

Whole Blood Donation Affects the Interpretation of Hemoglobin A1c

INTRODUCTION Several factors, including changed dynamics of erythrocyte formation and degradation, can influence the degree of hemoglobin A1c (HbA1c) formation thereby affecting its use in monitoring diabetes. This study determines the influence of whole blood donation on HbA1c in both non-diabetic blood donors and blood donors with type 2 diabetes. METHODS In this observational study, 23 non...

Hemoglobin A1c as a Screen for Previously Undiagnosed Prediabetes and Diabetes in an Acute-Care Setting

OBJECTIVE Hemoglobin A(1c) (HbA(1c)) is recommended for identifying diabetes and prediabetes. Because HbA(1c) does not fluctuate with recent eating or acute illness, it can be measured in a variety of clinical settings. Although outpatient studies identified HbA(1c)-screening cutoff values for diabetes and prediabetes, HbA(1c)-screening thresholds have not been determined for acute-care setting...

Measurement of Hemoglobin A1c

Evaluation of glycemia is used for the diagnosis and management of patients with diabetes. Glucose and hemoglobin A1c (HbA1c) provide complementary information and both are used to assess an individual’s glycemic status. The concentration of glucose in the blood indicates the subject’s glycemia at the time of blood sampling. However, blood glucose concentrations are modified by numerous factors...
