Abstract

A device includes a substrate that defines, at least in part, a microfluidic network including an inlet in communication with a first detection zone and with a second detection zone. A cobalt reagent and a nickel reagent are disposed within the microfluidic network. First electrodes are in communication with the first detection zone and second electrodes arc in communication with the second detection zone. The device is configured to receive a blood derived sample introduced to the inlet, partition the blood sample into first and second blood sample portions, form a first mixture including at least some of the first blood sample portion and at least some of the cobalt reagent, and form a second mixture including at least some of the second blood sample portion, at least some of the cobalt reagent and at least some of the nickel reagent.
