A summary of blood sugar measurement problems

What are the common methods for measuring blood sugar? In today's society, there are more and more patients with diabetes, but how to measure blood sugar is the most accurate way? Sometimes the results measured by the blood glucose meter may be different from the results of the venous blood test. , sometimes the needle is inserted shallowly, and as a result, less blood flows out, so just squeeze the needle site to squeeze out the blood and then measure. The following is a detailed introduction to common methods of measuring blood sugar!

 

1. Sometimes the results measured by the blood glucose meter may be inconsistent with the results of the venous blood test. In this case, the results of the venous blood test in the hospital shall prevail, because blood glucose meters have errors. Domestic blood glucose meters are set at about 20%, and imported blood sugar meters have an error of around 20%. The meter is generally around 15%.

 

2. Sometimes the needle is inserted shallowly, resulting in less blood flowing out. It is inaccurate to squeeze the needle site to squeeze out the blood and then measure the blood sugar. Because body fluids will flow out when the needle is inserted, resulting in low blood sugar measurements. Some blood glucose meters do not have the function of adding blood samples. Insufficient blood volume will affect blood sugar and the error will be large. Guangdong Province

 

3. Sometimes it is found that the same blood glucose meter measures different values several times in a row. Whether it is a home blood glucose meter or a hospital blood glucose measuring instrument, the blood glucose value measured each time may be different. Generally speaking, as long as the error does not exceed ±20%, it is within the normal range.

 

4. Sometimes patients will question why the values measured by our blood glucose meter are different from theirs. At this time, we should tell patients that blood glucose meters will have errors. As long as it does not exceed 20%, it is normal. Ask whether the blood glucose meter is calibrated regularly. Check whether the instrument test paper is within the validity period, whether the storage location is dry, whether the barcode is consistent, whether the battery is sufficient, whether the measurement method is correct, etc.

 

5. Sometimes when measuring blood sugar, we find that the measured value is very high, which makes us suspicious, and we take the test again because we are afraid that the patient will have opinions. At this time, we should explain it to the patient and ask him if he is willing to use another machine to test again for comparison. , and then we come back to check whether the blood glucose meter is qualified. When re-measurement, we must operate it in the correct way to minimize the error. If the difference between the two values is not large, it may be certain that the blood sugar level is indeed high, and it is necessary to report to the doctor to take measures. If the difference is large, it is necessary to contact the manufacturer to test the instrument.
