Under normal circumstances, the breakdown and anabolic metabolism of sugar in the human body is in a dynamic equilibrium and remains relatively constant. Serum glucose refers to the glucose concentration in the blood. Generally, venous blood is drawn on an empty stomach after fasting for 8-12 hours, and the specimen is submitted for inspection within 1 hour. Glucose measurement is one of the most important tests for diabetic diagnosis.

blood
Adults are 4.2-6.0mmoL / L; children are 3.3-5.5mmoL / L.
Abnormal results:
Elevation: seen in diabetes, chronic pancreatitis, hyperthyroidism, myocardial infarction, hypercortisolism, acromegaly, pheochromocytoma, glucagonoma; brain trauma, cerebral hemorrhage. Brain tumors, meningitis; pregnancy vomiting, dehydration, and general anesthesia; patients with liver cirrhosis often have elevated blood glucose, which may be related to increased growth hormone and glucagon.
Decreased: seen in various reasons caused by excessive insulin secretion or insufficient insulin hormone secretion, thyroid insufficiency, adrenal insufficiency, pituitary cachexia, acute progressive liver disease (acute yellow liver atrophy, acute hepatitis, liver cancer, phosphorus and Arsenic poisoning, etc.), neonatal hypoglycemia, etc.
(1) Fasting blood glucose is 6.1-7.0mmoL / L, which is considered as impaired fasting blood glucose.
(2) Fasting blood glucose 7.0mmoL / L, considered to be diabetes.
(3) Those with fasting blood glucose <2.8mmoL / L, or starvation for 24 hours, can develop typical hypoglycemia.
Need to check the crowd: those with abnormal blood glucose.
Unsuitable people: Generally there are no special people.
Contraindications before inspection:
(1) To measure fasting blood glucose, it is necessary to take a fasting blood test before 8 am, especially for patients treated with insulin, the fasting blood draw must be before the insulin injection time in the morning, otherwise the measured blood glucose will be increased and cannot be true. Reflect the control of diabetes.
(2) Blood sugar will also increase during various stress situations, such as mood swings, insomnia, fever, fatigue, etc. can affect blood sugar, so you should avoid strenuous exercise when sending to the hospital.
(3) If the blood glucose is measured 2 hours after a meal in order to determine whether there is diabetes, you can eat according to the normal amount of food (but not less than 100g staple food) or 100g steamed bread, and you can draw blood 2 hours after the meal.
(4) For diabetic patients who have been treated with oral hypoglycemic or insulin therapy, the measurement of blood glucose 2 hours after a meal is to observe the efficacy of the drug, so be sure to take the drug, eat as usual, and take blood 2 hours later. Fasting blood glucose and 2 hours postprandial blood glucose are best measured in 2 days.
Requirements during the inspection: Maintain a normal mentality and cooperate with the doctor to check.
2ml blood was collected on an empty stomach, sodium fluoride-potassium oxalate was used for anticoagulation, and plasma was measured.
Diabetes with tuberculosis, acquired liver coagulation factor abnormalities due to severe liver disease, drug-induced liver disease, myocardial infarction, alcoholic liver disease, diabetes
