How to measure blood sugar more accurately

1. The code of the newly purchased blood glucose meter needs to be adjusted before use; 2. Squeeze slightly from the root to draw blood; 3. Disinfect with medical alcohol; Follow these three factors when measuring blood glucose at home to ensure the accuracy of blood glucose measurement as much as possible. Is the blood glucose value you measure accurate? Do you really know how to measure blood glucose? In daily life, some omissions are inevitable in measuring blood glucose, which may lead to inaccurate values. Don't worry, listen to the experts to help you solve the problem. So, how to measure blood sugar more accurately? Let's have a simple understanding of this issue. I hope the following points will be helpful to everyone!

At present, the main methods used to accurately measure blood sugar levels are venous blood and fingertip blood. When we usually say whether the blood sugar level is normal, we use the blood sugar concentration in venous blood as a reference. Fasting venous blood glucose levels are relatively accurate. Fasting means not eating for more than 12 hours and not drinking for more than 6 hours. Fingertip blood is mixed blood, and its blood sugar level is about 10% higher than that of venous blood. However, the rapid blood glucose measuring instruments currently used have been preparatory processed during manufacturing, and the test results are actually calibrated data, the same as those of venous blood.

1. Inconsistent coding between the blood glucose tester and the blood glucose test strips will cause incorrect testing

Most patients have purchased instruments that need to be adjusted, and the instrument has a code, and the code on the instrument must match the code on the blood glucose test strip. Some people often have difficulty measuring, or forget to adjust the code when measuring, the code is inconsistent, and the measured postprandial blood sugar is different. Since it is impossible to ensure that every batch of pregnancy test strips responds consistently to glucose, the coding must be adjusted.

2. Poor extrusion during blood collection will result in incorrect testing

During the measurement process, the measuring method is incorrect. For example, when measuring, blood is usually drawn with the fingertips. It is necessary to squeeze slightly from the root and then pick the blood. However, some people pierce the blood shallowly and squeeze the blood sampling site with force, which may squeeze out tissue fluid. Therefore, the measured postprandial blood sugar is inaccurate. This is a problem of measurement method.

3. Misunderstanding of blood collection disinfection and sterilization leads to incorrect testing

Application of disinfectant. Blood sugar monitoring uses ethanol for disinfection and must wait until it dries. Some people may use iodine or mercurochrome to disinfect directly, which will also affect the blood sugar test results. Therefore, iodine disinfectant cannot be used for disinfection and sterilization, because the iodine in the pregnancy test paper will react with the pregnancy test paper, making the test value higher than the actual value.
