My grandfather has diabetes & his age is around 72 now. We all care too much for him. Though the hospital was very near to my residence where we usually visit to check his blood glucose but to save his time we bought a blood glucose monitoring device so we can check his diabetes at home itself. We use to check it whenever need but my grandfather never uses to feel good then I thought of taking him to the hospital and our doctor said that his sugar level has increased & we told the doctor that we just checked the sugar level & it was normal. We did check again and the device was showing the wrong information. We stopped using that device soon & then our doctor suggested us the most accurate blood glucose meter and now the results are accurate.
