Why is the data of blood sugar measurement at home different from that in the hospital?

Blood sugar measurement at home is not a finger blood test, and blood sugar measurement at hospital is taking venous blood with serum, and the results are different. The value measured in general hospitals is about1mmol/L. The blood glucose meter is convenient and simple for self-test of blood glucose in general families, and the blood glucose value can be measured at any time. The disadvantage is that it is not as accurate and comprehensive as the hospital's assessment of blood sugar level. You can't touch the test end with your hands, which will affect the test results. Finally, we should pay attention to the time of measuring blood sugar, such as fasting blood sugar before breakfast and postprandial blood sugar two hours after meals. The test time will also affect the test results. Self-detection of blood sugar is generally based on fingertip blood sugar, and the detected value will be somewhat biased, which is generally higher than that obtained by intravenous blood drawing, and may differ by about 0.5. It is recommended to draw blood from the hospital regularly.

Excessive drinking and excessive drinking may cause), the body will increase the secretion of insulin antagonist hormone to raise blood sugar, and if it is corrected excessively, it will lead to an increase in blood sugar in the morning. Fasting blood glucose and postprandial blood glucose are data at a certain time point, and the blood glucose data at different time points are different. Self-testing blood sugar is different from the methods and techniques of hospital examination, and it is difficult to control the time node at the same time node. Blood sugar is changing all the time, and there may be several values in a day. Blood sugar is only an index and value of western medicine. People should not live for indicators and values, but should start with changing the rules of eating and living, eating habits, mood and regulating the functions of viscera.

You can measure it again, or it may be caused by your inaccurate measurement method or the error of the instrument itself. If you are deeply suspicious of your measurement results, you can go to the hospital for testing. If there is something wrong with the instrument, replace it immediately! At present, blood sugar is basically measured by fingertips. If you are careful, you will find that the blood sugar value is different when measuring blood samples in different parts at the same time! There is a difference between fasting and eating breakfast. The blood sugar test on an empty stomach belongs to the normal range, and the blood sugar naturally rises after breakfast, so the test indexes are different.
