ABSTRACT:
An improved test device for the testing of a fluid having a cup and a cover lid, such cover lid having a reagent test strip chamber containing a reagent test strip, a fluid receipt chamber, a fluid channel containing a fluid-passing pad and a fluid contact chamber. An actuation cover with a window defined therein is positioned over the regent test strip chamber, fluid receipt chamber, fluid contact chamber, such window positioned over the color change area of the reagent test strip. The actuation cover forms a fluid-tight seal around a first end of the reagent test strip which protrudes into the fluid contact chamber. After the cup is filled with fluid and the cover lid is positioned thereon, the cup is inverted, causing fluid to flow into the fluid receipt chamber through an aperture in said cover lid. When the test device is turned upright, the fluid drains from the bottom of the fluid receipt chamber, through the pad, down the fluid channel and into the fluid contact chamber where it comes in contact with the protruding first end of the reagent test strip, such fluid to be drawn along the reagent test strip to accomplish the desired test to cause the appropriate color change to appear on such reagent test strip visible through the window in the actuation cover. An actuation button on the actuation cover can aid in some embodiments to draw fluid into the fluid receipt chamber. In other embodiments a valve, when actuated, can open the fluid receipt chamber to receive the fluid to be tested when the cup is inverted.
