  • (A) a base having adjacent slots therein of sufficient length for insertion of part of a test strip therein, wherein each slot is defined by (a) a floor, (b) raised walls depending upwardly from the floor to separate each adjacent slot from the next, and (C) at least one open end,(B) a multiplicity of test strips having an upstream and a downstream end, wherein a single test strip is inserted into each slot of the base so the upstream end of each test strip protrudes out of the open end of each slot, and wherein each test strip has a test zone and a control zone therein, and each test zone contains a binder specific for a different analyte;

    the protruding freestanding end of each test strip containing a sample addition pad for direct contact with the fluid to be analyzed;

    (C) a cover attached to the upwardmost surface of each raised wall of the slots of the base and extending to the open end of said base, wherein the cover retains the test strips within the slots and has a first transparent window formed therein through which the test zone and the control zone of each of the test strips can be viewed and(D) a cap enclosing the protruding ends of the test strips and removably attached to the open end of said base.
