First, the code of the new test paper is the "bridge" between the blood glucose meter and the test paper. If it is a new test paper, it is necessary to check whether the code of the blood glucose meter is consistent with the code of the test paper, otherwise it will also lead to inaccurate blood glucose monitoring. Check and adjust the code indicated by the blood glucose meter before measuring blood glucose to ensure that the code indicated by the blood glucose meter is consistent with the code on the test paper package.
Second, the test paper is overdue. Generally speaking, the validity period of well-known brand papers is only 12 months, and the validity period of canned papers is 3 months after opening. If the service life of the test paper is exceeded, it will also lead to inaccurate blood sugar monitoring. Store test papers correctly and apply them as planned. Test paper should be stored in a dry, dark, airtight room with room temperature of 4℃ ~ 30℃. After the canned test paper is opened, the date of Kaifeng city should be marked, and it will be used up within 3 months. After each use, the bottle stopper should be covered immediately to avoid absorbing dust or the test paper becoming cold due to moisture. The individually packaged test paper must be used up within the validity period.
Third, the way of blood collection is unreasonable. Take blood and stab the fingertips of the left ring finger. There are fewer sympathetic nerves in this position, and the pain is slightly lighter. When some patients measure blood sugar, they squeeze hard because they are not deeply tied and have less bleeding. As a result, the exudate is squeezed out, which jeopardizes the accuracy of the test. In addition, fingers should have a certain temperature. If the temperature is very low, the capillaries are easy to close, resulting in too little bleeding and inaccurate results.
Four, the blood glucose meter does not clean the blood glucose meter and test paper, and often suffers from environmental pollution such as dust, chemical fiber and dirt in the natural environment, especially inadvertently polluting the environment in blood night during the inspection process, which will endanger the inspection results. In addition, the blood glucose meter must be calibrated sometimes, for example, after replacing a new test paper, otherwise the test results will be inaccurate.
