- The Newly Established Diagnostic Criteria of Diabetes Mellitus (Rapid Progress of Diagnosis and Treatment in Diabetes Mellitus)
Diagnosis of diabetes mellitus Confirmation of chronic hyperglycemia is essential for the diagnosis of diabetes mellitus. When plasma glucose levels are used to determine the categories of glycemia, patients are classified as having a diabetes if they meet one of the following criteria: ((1)) fasting plasma glucose level of ≧ 126mg/dl; ((2)) 2-h value of ≧ 200mg/dl in 75g oral glucose tolerance test (OGTT) ; or ((3)) casual plasma glucose level of ≧ 200mg/dl. Normal type is defined as fasting plasma glucose level of <110mg/dl and 2-h value < 140mg/dl in OGTT. According to the current revision, in addition to the earlier listed plasma glucose values, hemoglobin A1c (HbAI1c) has been given a more prominent position as one of the diagnostic criteria. That is, ((4)) HbA1c ≧ 6.5% is now also considered to indicate diabetic type. The value of HbA1c, which is equivalent to the internationally used HbA1c (%) (HbA1c [NGSP]) defined by the NGSP (National Glycohemoglobin Standardization Program), is expressed by adding 0.4% to the HbAI1c (JDS) (%) defined by the Japan Diabetes Society (JDS).
