Sugar friends self-test blood glucose is one of the best and most important self-management methods for monitoring blood sugar, which is of great significance for monitoring the trend of blood sugar, measuring the impact of meals on blood sugar, and judging whether drugs are effective for blood sugar control. But many sugar friends will have such a question: is it more accurate to measure blood glucose with the 1st drop of blood or the 2nd blood?
The 2015 China Blood Glucose Monitoring Clinical Application Guide recommends that the arm collected from the blood should be naturally drooped for a moment after cleaning, then massage the blood collection site and use an appropriate blood collection device to obtain a sufficient amount of blood samples, and do not squeeze the blood collection site to obtain a blood sample, otherwise the inter-tissue fluid will dilute the blood sample and interfere with the blood glucose test results. The guidelines do not recommend which drop of blood glucose to use, and most of the instructions for the use of various blood glucose meters do not mention the use of the first or second drop of peripheral blood for measurement, and there is no uniform international regulation. Studies have shown that in the case of clean hands, avoid squeezing hard after puncture, and use the 1st and 2nd drops of blood to compare the blood glucose values measured by the intravenous blood draw, and there is no statistical difference. Therefore, we recommend that in the case of hand cleaning, the first drop of blood glucose can be used, and the standardized use of the first drop of blood glucose can save the operation time, reduce the pain of the patient, and save medical resources. However, if you do not wash your hands or do not have the conditions to wash your hands, you should avoid contact with sugary substances, avoid squeezing hard, and use the second drop of blood to measure blood glucose.
In daily life, sugar friends should also pay attention to regularly check whether the test strips, needles, etc. are expired, damp, and whether the blood glucose meter and the test strips match. The blood glucose meter should be calibrated and cleaned regularly so as not to affect the accuracy of the test results. When measuring blood glucose, pay attention to rotating fingers, gently press the wound with a cotton swab after measuring blood glucose, can not rub, and record the measured blood glucose value on time according to the doctor's requirements, observe the blood sugar trend, and provide a basis for the doctor's diagnosis and treatment.
