Seasonal patterns in monthly hemoglobin A1c values.
The purpose of this study was to investigate seasonal variations in population monthly hemoglobin A(1c) (A1c) values over 2 years (from October 1998 to September 2000) among US diabetic veterans. The study cohort included 285,705 veterans with 856,181 A1c tests. The authors calculated the monthly average A1c values for the overall population and for subpopulations defined by age, sex, race, ins...
متن کاملInfluence of variables on hemoglobin A1c values and nonheterogeneity of hemoglobin A1c reference ranges.
INTRODUCTION Hemoglobin A1c (HbA1c) values are influenced by analytical interferences such as HbF and hemoglobin variants and clinical factors such as increased red cell turnover. Although less well-known, demographic factors such as race, age, and sex also influence HbA1c values. The HbA1c reference range should be homogenous in the United States based on the use of National Glycohemoglobin St...
متن کاملHemoglobin Himeji and inconsistent hemoglobin A1c values: a case report
BACKGROUND Hemoglobin A1c is used to evaluate the glycemic control in patients with diabetes and is a risk marker for chronic complications of diabetes. Hemoglobin variants are reported to falsely lower or increase hemoglobin A1c test results. We present a case report of a patient with diabetes with discrepancy between fasting plasma glucose and hemoglobin A1c due to the presence of hemoglobin ...
متن کاملInterpretation of hemoglobin A(1c) (HbA(1c)) values among diabetic patients: implications for quality specifications for HbA(1c).
BACKGROUND Few studies have examined patients' views, knowledge, and understanding of glycohemoglobin A(1c) (HbA(1c)) testing. We explored such issues in patients with type 1 diabetes and used their statements to estimate analytical quality specifications for HbA(1c) testing. METHODS We recruited 201 patients from a hospital outpatient clinic. A questionnaire was used to collect information o...
متن کاملWhole 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...
