One, is that there is an error between the two glucose meters. Different glucose meters have different sensitivities and the results will vary.

Secondly, there is also a difference between hospital blood glucose testing, where venous blood is drawn, and home blood glucose monitoring, where blood is taken from the fingertips. Therefore, as a diagnosis of diabetes, blood needs to be drawn from a vein for testing.

Third, blood glucose fluctuates, and when you eat a meal, there is a large rise in blood glucose, especially in hyperglycemic and diabetic patients, which is greatly influenced by the meal and food intake. The rise in blood glucose peaks at two hours after eating a meal and then gradually decreases. The results you measured at home yesterday will not be exactly the same as the results you measure at the hospital today. This is because there will be differences between what you ate yesterday and what you eat today, e.g. the length of time since you took your medication is also relevant. For example, if you fasted in the morning, how long you fasted for, whether you exercised before the fasting test (e.g., walked to the hospital) and whether you didn't exercise during the home test, and many other factors can make a difference.

Four, the time you take your blood glucose is not the same as the time you take it in the hospital, and that can make a difference. Unless you use the same instrument, the same test strips, and take blood at the same time. But that's not necessary and you can't do it.

Therefore, diabetic patients to monitor blood glucose, to be in the meal before and after the meal (especially one hour after the meal, two hours), before taking medication, after taking medication at different times for monitoring, do not require the same results every day, but require smooth and up to standard. If fluctuations within a reasonable range do not overly in the call. In addition to diabetic patients, every three months or half a year to check hemoglobin is also necessary, blood glucose and hemoglobin are normal you can rest assured.

Thanks for the invite.

It is possible for different blood glucose meters to monitor different data!

The discrepancy may be related to several factors:

• Differences in blood glucose testing technology between home glucose meters and hospital biochemistry tests;
  
• The body's blood glucose is in flux from moment to moment, and measurements vary from time to time;
  
• There are also differences in the standardization of blood glucose testing between homes and hospitals!
  

We need to know when this discrepancy occurs:

• Generally speaking, the error of home blood glucose meter relative to the biochemical index of hospital is withinWithin 1mmol/lis acceptable;
  
• For the existence of errors, the appearance of such errors is generally related to the stability of the blood glucose meter we use, but also related to the method of test strip application.In general, we alsoDifficult to calibrate；
  
• For the case of large error: we recommend more testing a few times, because not every error is so large, large error may be related to the poor stability of the blood glucose meter detection; In addition, there is also in the blood glucose is particularly low or high error is relatively large, such as blood glucose more than ten mmol / l, or 3.9 mmol / l a little bit, the middle part of the blood glucose is still okay;
  
• Lastly, Dr. Mei would also like to tell you that the purpose of home blood glucose testing is primarily toObserve the level of blood glucose control throughout the daythat fluctuations within a certain range are generally normal and acceptable.Don't focus too much on some specific values!
  

I hope my answer is helpful to you!

The blood glucose meters in hospitals also vary, so take it as a reference and know the general range. You should know the general range.
