Abstract
The present disclosure relates to analytical testing devices comprising microfluidics and methods for performing an assay on a fluid sample received within the microfluidics, and in particular, to mitigating drift of fluid samples over a sensor by incorporating a bypass channel into the microfluidics. For example, a test cartridge device is provided that includes a fluid sample entry port and holding chamber connected to a bifurcation junction of a sensor channel and a bypass channel. The sensor channel includes an upstream region and a downstream region, and an analyte sensor is in the upstream region. As a cross-sectional area of the bypass channel is greater than the cross-sectional area of the downstream region of the sensor channel, the bypass channel is a preferred path for excess sample flow and pressure, and thus sample drift above the analyte sensor is mitigated.
