A device for testing a sample of saliva, comprising: a cup including a containment bottom and a plurality of unitary upright side walls (32, 34) extending upward from the containment bottom, said plurality of side walls including a first side wall, said plurality of side walls and said containment bottom defining a cavity, said containment bottom intersecting each of said plurality of side walls (32, 34), a junction line being located at a lowermost extremity of said cavity when the cup is in an upright position, said containment bottom intersecting the first side wall along the junction line, said plurality of side walls defining a continuous upper edge of said cup; a holder disposed in said cavity of said cup, said holder including a front face adjacent said first side wall of said cup, said front face including a plurality of parallel ribs that define a plurality of parallel elongate channels, said plurality of parallel elongate channels each defining a channel axis that extends perpendicular to said junction line, each of said plurality of parallel elongate channels being adapted to hold a corresponding test strip so that a detection end of said corresponding test strip is proximate said junction line; and a cap portion joined to said upper edge of said cup, said cap portion defining an access port, a through passage structure comprising a hollow tube that passes through said cap portion, said through passage structure including a proximal end and a distal end concentric about an insertion axis, said proximal end of said through passage structure including said access port of said cap portion, said distal end being at the containment bottom; a sampling stem having a proximal portion and a distal portion, said distal portion including a sampling swab, said sampling stem is configured for insertion through said through passage structure, the containment bottom including a seating portion configured for squeezing engagement with the sampling swab, characterized in that said first side wall of said plurality of side walls (32, 34) is planar and the plurality of side walls (32, 34) includes an arcuate side wall opposite the planar first side wall, the containment bottom comprising an upwardly facing inclined surface, the seating portion being formed on the inclined surface, the inclined surface extending from and being inclined from the junction line at the planar first side wall to the arcuate side wall opposite the planar first side wall of the plurality of side walls (32, 34), whereby the inclined surface is part of a saliva pathway leading saliva, which is squeezed out of the sampling swab by the seating portion, down the inclined surface to the junction line. a cup including a containment bottom and a plurality of unitary upright side walls (32, 34) extending upward from the containment bottom, said plurality of side walls including a first side wall, said plurality of side walls and said containment bottom defining a cavity, said containment bottom intersecting each of said plurality of side walls (32, 34), a junction line being located at a lowermost extremity of said cavity when the cup is in an upright position, said containment bottom intersecting the first side wall along the junction line, said plurality of side walls defining a continuous upper edge of said cup;
