In today's society, there are more and more patients with diabetes, but how to measure blood sugar most accurately? 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 the result is If there is little blood flowing out, squeeze the needle site to squeeze out the blood and then measure it. The following is a detailed introduction to the 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. At this time, 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 glucose meters are generally around 15%.
2. Sometimes the needle is inserted shallowly, resulting in little blood flowing out. Just squeeze the needle site to squeeze out the blood and then measure. Blood sugar measured this way is inaccurate. 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. Sometimes you will find that the same blood glucose meter gives 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.
3. Sometimes patients will question why the values measured by our blood glucose meter are different from theirs. At this time, we should tell the patient that the blood glucose meter will have errors. As long as it does not exceed 20%, it is normal. Ask whether the blood glucose meter is calibrated regularly, whether the meter test paper is within the validity period, whether the storage location is dry, whether the bar code is consistent, whether the battery is sufficient, and whether the measurement Whether the method is correct etc.
4. Sometimes when measuring blood sugar, I find that the measured value is very high, which makes me suspicious, and I am afraid that the patient will have objections when I measure it again. At this time, we should explain to the patient and ask him if he is willing to use another machine to measure again for comparison. Then we will come back to check whether the blood glucose meter is qualified. When re-measurement, we must operate it in the correct way and minimize the risk. Small 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.
