1. A biosensor comprising:
- a first sensor comprising a first operation electrode and a first counter electrode that is spaced apart from the first operation electrode;
a second sensor comprising a second operation electrode and a second counter electrode that is spaced apart from the second operation electrode, wherein a surface of the second operation electrode is coated with a detecting reagent layer comprising an enzyme; and
a controller receives a first detect signal from the first sensor and a second detect signal from the second sensor, wherein the controller outputs a quantitative analysis value corresponding to the first detect signal and a qualitative analysis value corresponding to the second detect signal.
