The household Glucose meter, which is simple to operate, small and portable, and displays the test results in 5 seconds, has become a "necessity" for many elderly people and diabetes patients. However, the reporter's investigation found that although the measurement results of the household Glucose meter can have some errors with the hospital test, the current results are too far off the mark. ■ The 82 year old Mr. Liu suffers from diabetes when the invasive Glucose meter has error test paper. He bought an invasive Glucose meter, but the measurement results were shocking. I tried for a few days and tested three times in a row within 10 minutes. The results were all different, fluctuating high and low, "he told reporters. Old Master Liu was not sure, so he took the Glucose meter to the hospital for venous blood test. The hospital test results show that the blood sugar value is 6.5 mmol/L. He immediately took a home Glucose meter to measure -7.6 mmol/L, 1.1 mmol/L higher. Uncle Wang is also often troubled by the measurement results of the invasive Glucose meter. He used the Glucose meter to measure the Glucose test#Fasting blood sugar to 8.1 mmol/L, which is much higher than the usual measurement results. Quickly went to the hospital for a test, and the result showed 6.2 mmol/L. Now, he has summed up the experience: "The Glucose meter used at home, each measurement result minus 2 mmol/L, is the accurate result." The reporter visited 8 pharmacies in Chaoyang District, Dongcheng District and other districts, and found that the home Glucose meter for finger tip blood is generally sold at a low price, mostly about 50 to 200 yuan. However, the price of the test paper is not cheap. Due to the large amount and fast consumption of test strips, some elderly people may want to purchase other cheaper test strips to replace them, or may want to repeatedly use test strips, which may also affect the test results. Meng Liuhuan, a general practitioner at the Xueyuan Road Street Health Service Center in Haidian District, told the reporter that nearly 30% of the residents had reported the inaccurate measurement of the Glucose meter. In fact, it is common that the household Glucose meter for rapid blood glucose detection has errors with the hospital measurement results. Before marketing, relevant comparative tests must be carried out according to regulations. The blood glucose measurement results of home Glucose meter and venous blood collection are allowed to have certain errors. As long as the difference between the results is within the range of 10% to 15%, they are in line with the certification audit. "When you go to the hospital to measure blood sugar, you can take your own Glucose meter to make a comparison." Meng Liu Huan said that you can use a home Glucose meter and a hospital Glucose meter to measure blood sugar at the same time, and compare the errors of the two. If the error is too large, we should consider whether there is a problem with the Glucose meter. ■ The non-invasive Glucose meter is very convenient to wear, but it is uncertain. In recent years, the non-invasive Glucose meter, which claims "no needling" and "sugar friend gospel", has sprung up. Some businesses sell more than 5000 non-invasive Glucose meter per month. This kind of Glucose meter is small in size. Users can wear it on an arm to measure blood glucose values in real time for 24 hours, and the data can also be displayed in mobile phones through applications. In terms of price, the non-invasive Glucose meter is not cheap. The reporter visited 8 pharmacies and learned on the e-commerce platform that the price range of non-invasive Glucose meter is very large, some selling at 400 yuan, some as high as 3000 yuan. In a drugstore near Dongsishitiao, the reporter saw a non-invasive Glucose meter with a price of 499 yuan. If used by oneself, ordinary
