Type 2 Diabetes ADA Diagnosis Criteria
Diagnostic criteria by the American Diabetes Association (ADA) include the following:
A fasting plasma glucose (FPG) level of 126 mg/dL (7.0 mmol/L) or higher, or
A 2-hour plasma glucose level of 200 mg/dL (11.1 mmol/L) or higher during a 75-g oral glucose tolerance test (OGTT), or
A random plasma glucose of 200 mg/dL (11.1 mmol/L) or higher in a patient with classic symptoms of hyperglycemia or hyperglycemic crisis, or
A hemoglobin A1c (HbA1c) level of 6.5% (48 mmol/mol) or higher
至於A1C尚未到達 6.5 的, 又比正常人高, 稱為糖尿病前期 preDM stage.
根據美國糖尿病學會定義. A1C 介於 5.7%~ 6.5% 稱為糖尿病前期.
A1C 可反應過去 2-3 個月的血糖變化. 但在某些情況判讀A1C要小心
例如紅血球壽命較短的個體. A1C 會假性正常 (例如, 實際上是糖尿病, 但A1C偏低)
Finally: A1C is also defined as ‘estimated average glucose,’ or eAG
Another term you may come across when finding out your A1C is eAG. Your doctor might report your A1C results as eAG. eAG is similar to what you see when monitoring your blood sugar at home on your meter. However, because you are more likely to check your blood sugar in the morning and before meals, your meter readings will likely be lower than your eAG.
