Abstract
A card is provided for detecting the existence and/or identity of microbial presence, having a base for receiving thereon a fluidic sample, a transparent cover to overlay the base, formed with a top layer, a bottom layer, and an adhesive layer therebetween, wherein a portion of the bottom layer is formed such that a portion of the adhesive layer is not covered by the bottom layer, and a media applied is to and retained by that portion of the adhesive layer which is not covered by the bottom layer, that media serving to gel the fluidic sample and/or support growth of a micro-organism whose existence and/or identity is being tested by the card. To facilitate manual and/or automated counting of visual indications of micro-organisms, a black ink grid system can be applied which does not diffuse in the presence of the fluidic sample and/or the media, but at the same time which readily is removable from the base when removal is desired.
