INTRODUCTION TO THE SYSTEM
Intended Use
The system is intended for use outside the body (in vitro diagnostic
use). It should be used only for testing glucose (sugar) and only
with fresh capillary whole blood samples (from the finger, the palm,
the forearm, the upper arm, the calf and the thigh). The system is
intended for use in the home and in clinical settings. It should not be
used for the diagnosis of diabetes or for the testing of newborns.
AST in this system can be used only during steady-state blood glucose
conditions described in the section of “About Alternative Site Testing
(AST).”
Principle of Measurement
The test is based on the measurement of electrical current
generated by the reaction of glucose with the reagent of the strip. The
meter measures the current and displays the corresponding blood
glucose level. The strength of the current produced by the reaction
depends on the amount of glucose in the blood sample.
