A Review of the Challenge in Measuring Hemoglobin A1c

A review of the challenge in measuring hemoglobin A1c.

The attraction of the simple biochemical concept combined with a clinical requirement for a long-term marker of glycolic control in diabetes has made hemoglobin A1c (HbA1c) one of the most important assays undertaken in the medical laboratory. The diversity in the biochemistry of glycation, clinical requirements, and management demands has resulted in a broad range of methods being developed si...

Another step toward standardization of methods for measuring hemoglobin A1c.

Current aspects in hemoglobin A1c detection: a review.

Type 2 diabetes mellitus (T2DM) is a pressing health issue that threatens global health and the productivity of populations worldwide. Despite its long-recognized role in diabetes management, glycated hemoglobin (HbA1c) only received WHO endorsement as a T2DM diagnostic tool in 2011. Although conventional plasma-specific tests have long been utilized to diagnose T2DM, the public should be infor...

A review of variant hemoglobins interfering with hemoglobin A1c measurement.

Hemoglobin A1c (HbA1c) is used routinely to monitor long-term glycemic control in people with diabetes mellitus, as HbA1c is related directly to risks for diabetic complications. The accuracy of HbA1c methods can be affected adversely by the presence of hemoglobin (Hb) variants or elevated levels of fetal hemoglobin (HbF). The effect of each variant or elevated HbF must be examined with each sp...

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...
