1. A biosensor, comprising:
- a base layer;
a first capillary disposed on the base layer configured to electrochemically determine a concentration of a first analyte in a blood sample, wherein the first capillary includes a first set of at least one electrode; and
a second capillary disposed on the base layer configured to determine a value correlating to the hematocrit level of the blood sample, wherein the second capillary includes a second set of at least one electrode.

Abstract
Methods and devices for determining the concentration of a constituent in a physiological sample are provided. The blood sample is introduced into a test strip with portions of the blood sample being directed to both a first capillary and a second capillary. The first capillary configured to electrochemically determine a concentration of a first analyte in a blood sample by measuring a signal across a set of electrodes. The second capillary is configured to determine a hematocrit value of the blood sample by measuring a signal across a second set of electrodes.
