1. A biosensor for quantifying a concentration of an analyte in a blood sample, comprising:

  • a base layer having a distal end, a proximal end, and a top surface extending generally from the distal end to the proximal end;

    a first chamber located above the top surface and having a first distal end and a first proximal end;

    a second chamber located above the top surface and having a second distal end and a second proximal end, wherein the second proximal end is generally located at the proximal end of the base layer and the second distal end is fluidly connected to the first proximal end of the first chamber;

    a first pair of electrodes disposed on the base layer and configured to determine a value corresponding to a hematocrit level of the blood sample, wherein a first portion of one of the first pair of electrodes is located in the first chamber, a second portion of the one of the first pair of electrodes is located in the second chamber, and the other of the first pair of electrodes is located in the second chamber; and

    a second pair of electrodes disposed on the base layer and configured to determine a value corresponding to a concentration of the analyte in the blood sample, wherein one of the second pair of electrodes is the one of the first pair of electrodes having the first portion located in the first chamber and the second portion located in the second chamber, and the other of the second pair of electrodes is located in the first chamber.
