Abstract:
1. A device for determining the presence or amount of an analyte in a sample, comprising: a first cup comprising an interior for holding a liquid sample, a top, one or more sidewalls, and a bottom; a second cup having a top, one or more sidewalls, and a bottom, the first cup being disposed within the second cup; at least one reservoir for containing an aliquot of sample located between the first and second cups, the first cup further comprising an aperture venting from the interior of the first cup into an opening in the at least one reservoir; a valve assembly interfacing with the at least one reservoir for regulating liquid communication of the aliquot of sample from the interior of the first cup to the at least one reservoir via the aperture; one or more test elements comprising a sample application zone, for determining the presence or amount of an analyte in the liquid sample; and a passageway connecting the at least one reservoir and the sample application zone; wherein the first cup has a first position in which the valve assembly allows liquid communication between the interior of the first cup and the at least one reservoir via the aperture being radially aligned with the opening, and a second position in which the valve assembly seals the at least one reservoir from liquid communication with the interior of the first cup, the aperture and the opening being radially unaligned, and wherein upon rotation of the first cup within the second cup, the first cup transitions from the first position to the second position and the valve assembly provides liquid communication between the at least one reservoir and the one or more test elements via the passageway.
