متن کاملMeasurement 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...
متن کاملComparison of costs of hemoglobin A1c determination by point-of-care testing (POCT) and standard hemoglobin A1c analyzer
OBJECTIVE The use of the levels of hemoglobin A1c for the monitoring of glycemic control in patients with diabetes mellitus (DM) is an accepted method of clinical usefulness. A study was performed to assess the relative costs of hemoglobin A1c determination by diagnostic testing at or near the site of patient care (point-of-care testing, POCT) and using the standard hemoglobin A1c analyzer. MET...
متن کاملDetermination of percent hemoglobin A1c using a potentiometric method.
We report a potentiometric method for measuring the hemoglobin A1c (HbA1c, glycated hemoglobin) concentration, hemoglobin (Hb) concentration, and percent HbA1c (%HbA1c) in human blood hemolysate. The %HbA1c is important for diagnosis and management of diabetes mellitus. Alizarin red s (ARS) is used as a redox indicator. Phenylboronic acid (PBA) binds to both ARS and HbA1c via diol-boronic acid ...
متن کاملA 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...
