Abstract
Aim:
To evaluate comparability of NGSP-certified method and IFCC-calibrated method.
Methods:
HbA1c was measured on two analyzers (n=50). Comparability was tested by Deming regression, bias estimation and Friedman test.
Results:
A strong correlation and good agreement between two methods was demonstrated.
Conclusion:
NGSP and IFCC-derived NGSP HbA1c can be used interchangeably.

01:29Hyperglycemia
Hyperglycemia is an abnormally high blood glucose level. It is diagnosed by fasting glucose ≥126 mg/dL, 2-hour oral glucose tolerance test (or OGTT) ≥200 mg/dL, random glucose ≥200 mg/dL with symptoms, or HbA1c ≥6.5%. However, HbA1c results may be unreliable in certain conditions, such as anemia or hemoglobinopathies, and the diagnosis should be confirmed unless classic symptoms are present. Postprandial hyperglycemia is typically considered significant when glucose levels exceed 180 mg/dL two...
01:26Hypoglycemia
Hypoglycemia is a blood glucose level below 70 mg/dL. It commonly occurs in individuals using insulin or insulin-secreting drugs, but may also arise in non-diabetic conditions. People with type 1 diabetes are at the highest risk because they depend on exogenous insulin. People with type 2 diabetes are also at risk, especially when treated with insulin or medications such as sulfonylureas, which increase insulin release regardless of blood glucose levels. It develops when insulin levels exceed...
