The Precision Xtra Blood Glucose and Ketone Monitoring System does not require coding and features simple 2-step testing - simply insert a strip, add an adequate blood sample, and the test begins; a smart icon driven menu with intuitive setup and easy navigation; and easy-to-use buttons that make it simple to review results with the ability to scroll back and forth. The monitor has a large, backlit display and stores 450 tests along with their dates and times, and you can also download test results to your computer (data cable sold separately) if more data storage is required. This system produces glucose testing results in approximately 5 seconds and ketone results in about 10 seconds, but it does NOT include Precision Xtra Blood Glucose Test Strips or Precision Xtra Blood Ketone Test Strips.
