ABSTRACT:
A specimen test slide has a front panel and a rear panel. The front panel has a plurality of openings. Sheet means underlie each of these openings for the reception of a specimen. The portion of the sheet under each opening carries a test reagent. A hinged cover overlies the openings. The rear panel has tab means opposite the said openings which are pivotable to expose the underside of the sheet to permit the application of a developing solution. The reagent at each location may be the same or different. When the reagents are different, they can be separately printed on the sheet to underlie different openings. A single sheet is disclosed underlying all of the openings with the employment of a barrier to limit the migration between adjacent portions of the sheet. The use of separate sheets under each opening is also disclosed.
