At the very least, how does a glucose meter work?
People use portable blood glucose meters, called glucometers, to check their blood sugar levels. These work by analyzing a small amount of blood, usually from a fingertip. A lancet lightly pricks your skin to obtain the blood. Meters tell you your current blood sugar.
Then, what does Hi mean on a glucose meter? b. "HI" or "LO" meaning that the result is above or below the upper or lower reading limits of the ACCU- CHEK Inform II system (>600 mg/dL or <10 mg/dL). Obtaining a lab glucose is recommended when HI or LO is displayed.
Even in the case, what are the different types of glucose meters?
How do blood glucose meters work? We can divide them into three different types: invasive, non-invasive and continuous. Invasive: the measurement is made using a blood sample taken using a lancing device, lancets and test strips. These elements are often sold in kit form at the time of the first purchase.
