Self contained in-vitro diagnostic device
A portable apparatus for measuring a glucose level of a user having: a card-like member; a processor within the card-like member; at least one glucose sensor comprising a reagent, the glucose sensor generating a signal indicative of a measured glucose level upon application of a blood sample to the glucose sensor, wherein the glucose sensor is fixed to the card-like member and operably coupled to the processor; and at least one cover alterable between a first position in which the glucose sensor is covered and a second position in which the glucose sensor is exposed for use.
1. A portable apparatus for measuring a glucose level of a user comprising:
a card-like member;
a processor within the card-like member;
at least one glucose sensor comprising a reagent, the at least one glucose sensor generating a signal indicative of a measured glucose level upon application of a blood sample to the at least one glucose sensor, wherein the at least one glucose sensor is fixed to the card-like member and operably coupled to the processor; and
a calibration glucose sensor fixed to the card-like member so as to be unusable by the user and wherein calibration data unique to the at least one glucose sensor is generated by the calibration glucose sensor.
2. A portable apparatus for measuring a glucose level of a user comprising:
a card-like member;
a processor within the card-like member;
at least one glucose sensor comprising a reagent, the at least one glucose sensor generating a signal indicative of a measured glucose level upon application of a blood sample to the at least one glucose sensor, wherein the at least one glucose sensor is fixed to the card-like member and operably coupled to the processor;
