You prick your finger with a small, sharp needle (called a lancet) and put a drop of blood on a test strip. Then you put the test strip into a meter that shows your blood sugar level. You get results in less than 15 seconds and can store this information for future use. Some meters can tell you your average blood sugar level over a period of time and show you charts and graphs of your past test results. You can get blood sugar meters and strips at your local pharmacy. https://www.streetinsider.com/FMR+Wire/Blood+Balance+Formula+Reviews-Don%E2%80%99t+Buy+Until+You+Read+this%21/17126919.html
