Blood glucose monitoring is a very important teaching link in diabetes and poc point of care daily diagnosis and treatment. Good blood glucose management and control can effectively delay the occurrence and development of acute and chronic complications of diabetes.
The summary and analysis of commonly used clinical blood glucose monitoring methods are as follows:
Blood sugar (GLU)
Clinical blood glucose measurement generally refers to the measurement of glucose in the blood. The measurement of glucose concentration in the blood is the most important indicator for understanding carbohydrate metabolism in the body and reflects the patient's blood sugar level during the test. The current methods for detecting blood sugar mainly include the following:
Intravenous blood sugar:
The main research adopts the enzymatic method, among which the hexokinase method is the reference learning method for the determination of glucose, and the blood glucose of intravenous patients is measured. The calculation accuracy and precision of this method are high, and the specificity is significantly higher than that of the standard glucose by the oxidase method. . Mild hemolysis, lipemia, jaundice, sodium fluoride, heparin, EDTA and oxalate do not interfere with the determination of this method.
Peripheral blood sugar:
The small blood glucose meter measures blood glucose with peripheral whole blood, which has a short detection time and small size of the instrument. It is mostly used for patient self-monitoring or bedside examination of inpatients. However, when the blood glucose meter is used for measurement, due to different samples, electrode interference, incorrect operation of the patient, etc., a deviation of about 15% to 20% can be caused. It is usually used to monitor the patient's fasting, pre- and post-prandial blood glucose fluctuations. It is fast Monitoring indicators.
Do you know everything about monitoring your blood sugar?
The clinical diagnosis of diabetes should be based on the results of venous blood glucose rather than capillary blood glucose levels.
When analyzing the results of blood glucose measurement, it is also necessary to pay attention to the fact that there may be a temporary increase in blood glucose under acute infection, trauma or other stress conditions. Diabetes cannot be diagnosed with blood glucose at this time, and it must be rechecked and confirmed after the stress is eliminated.
Hemoglobin (HbA1c) during glycation
Glycated hemoglobin is a combination of hemoglobin in red blood cells and sugar in serum. It forms a continuous and irreversible glycosylation reaction through slow, and its content depends on the blood glucose concentration and the contact time between blood glucose and hemoglobin, and has nothing to do with the time of blood draw, whether the patient is fasting, whether to use insulin and other factor. Therefore, hba1c can reflect the average blood glucose level of the past 8-12 weeks. Glycated hemoglobin is the "gold standard" for long-term blood sugar control.
