One of the following conditions can be diagnosed as diabetes:
1, with typical diabetic symptoms, and the blood sugar is always higher than11.1mmol/l (200 mg/dl).
2. When fasting blood glucose is checked, it is higher than 7.8mmol/L( 140mg/dl) twice or more.
3. If the fasting blood glucose does not exceed 7.8mmol/L, and the patient is suspected to have diabetes, oral glucose tolerance test can be done. 2 hours after taking sugar, the blood sugar exceeded11.1mmol/L. If you don't have symptoms of diabetes, you need to have another blood sugar exceeding11.1mmol/L. The above blood sugar value is the venous plasma glucose concentration.
Diagnostic criteria of diabetes proposed by American Diabetes Association (1997)
1, symptoms of diabetes, and any blood sugar ≥11.1mmol/L.
2, fasting blood glucose ≥ 7.0 mmol/L. ..
3, glucose tolerance test 2 hours blood sugar ≥11.1mmol/l ... ogtt is still in accordance with the requirements of the World Health Organization.
What is the standard value of blood sugar? Patients who meet one of the above criteria will repeat the above examination on another day. Only in this way can the patients with diabetes be psychologically informed and play a positive role in the treatment of diabetes.
This diagnostic standard was issued by WHO and IDF in 1999, and was recognized by Diabetes Society of Chinese Medical Association in the same year, and it is recommended to be implemented in China.
Venous (whole blood) capillary vein (plasma (diabetic fasting ≥6. 1 ≥6. 1 ≥ 2 hours after taking sugar ≥10.0 ≥1.1≥ (impaired glucose tolerance after taking sugar on an empty stomach
Several explanations of diagnostic requirements
Diagnosed with diabetes:
1, typical symptoms, fasting blood glucose 126mg/dl(7.0 mmol/l) or postprandial blood glucose ≥ (11.1mmol/l).
2. There are no typical symptoms. Just repeat fasting blood glucose 126mg/dl(7.0 mmol/l) or postprandial blood glucose11.1mmol/L, and those who still reach the above values can be diagnosed as diabetes.
3. No typical symptoms, only fasting blood glucose 126mg/dl(7.0 mmol/l) or postprandial blood glucose (1.1mmol/L). Glucose tolerance test 200 mg/dl (11.65438) for 2 hours.
(2) Diabetes can be ruled out:
1 For example, after 2 hours of glucose tolerance, the blood sugar is between140-200mg/dl (7.8-1.1mmol/L), which indicates impaired glucose tolerance; If the fasting blood glucose110-126 mg/dl (6.1-7.0 mmol/l) is impaired, it is not diagnosed as diabetes.
2. If the postprandial blood sugar
Injection and release
1, and if the blood sugar value exceeds the above indicators, it can be diagnosed as severe symptoms and obvious hyperglycemia.
2. In the case of acute infection, trauma, surgery or other stress, although obvious hyperglycemia is detected, it cannot be immediately diagnosed as diabetes.
3, asymptomatic people can't be diagnosed according to a blood sugar value, but also must exceed another diagnostic criteria.
4. Most children with diabetes have severe symptoms, high blood sugar, positive urine sugar and urine ketone body, so glucose tolerance test is not needed. A few patients with mild symptoms need to be tested for fasting blood glucose or glucose tolerance test.
