Patent ID: 8920319

Claim:
A device of an in vivo continuous glucose monitoring system that determines glucose level by way of in vivo glucose sensors and in vitro glucose test strips, comprising: a test strip receiving port that receives coded in vitro glucose test strips that require user calibration action to calibrate the in vitro test strips and non-coded in vitro glucose test strips that do not require user calibration action to calibrate the in vitro test strips; a processor configured to determine glucose concentration from an electrical signal obtained from in vivo glucose sensors at least partially inserted into the skin of a user, and from both the coded and the non-coded in vitro glucose test strips received in the test strip receiving port by first determining if a received in vitro glucose test strip is a coded or a non-coded test strip, selecting a coded or a non-coded processing algorithm to process a signal from the in vitro test strip once determined, and processing the signal from the in vitro test strip to determine an in vitro glucose value; and a user interface configured to communicate the glucose concentration determined by the processor.
