I bought a blood glucose meter for my family for the first time. I looked up a lot of evaluations on the internet and chose a blood glucose meter under the recommendation of netizens. In fact, the main concern of blood glucose meter is accuracy. The accuracy of blood glucose monitoring meets the domestic market blood glucose measurement standards. The tolerance range of ISO 20 13 is +- 15%, and the possible error range of blood glucose meter is only +- 15%. Allow samples to be added to the same test paper twice within 30 seconds. My parents said it was convenient, so I finally didn't have to go to the hospital often. Your adoption is my motivation.
