摘要：
The present invention provides a biofluid sensing device capable of concentrating a biofluid sample with respect to a target analyte, so that the analyte can be accurately detected or measured by EAB sensors. Methods for using such a device provide qualitative information about the presence of the analyte, and/or quantitative information about relative concentrations of the analyte in the biofluid. The disclosed device includes a concentration channel for concentrating the biofluid sample, as well as a selectively permeable membrane, one or more EAB sensors, and one or more secondary sensors carried on a water-impermeable substrate. A method for using the disclosed device to collect a biofluid sample, concentrate the sample relative to a target analyte, and measure the target analyte is also disclosed.
