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.

Claims

1. A specimen test slide comprising:

a front panel,

a rear panel,

said front panel having a plurality of openings,

sheet means between the front and rear panels underlying each of said openings for the reception of a specimen and with the portion of the sheet under each opening carrying a test reagent,

a hinged cover adapted to overlie a portion of the front panel and said openings, and

tab means in the rear panel opposite said openings and pivotable to expose the underside of the sheet.

2. The slide of claim 1 in which the sheet means is a single sheet underlying all of the openings and the reagent under each opening is different.

3. The slide of claim 2 in which the sheet has a barrier to prevent the migration of material from the portion of the sheet under one opening to a portion of the sheet under another opening.

4. The slide of claim 1 in which the sheet means is a single sheet underlying all of the openings and the reagent under each opening is the same.

5. The slide of claim 4 in which the sheet has a barrier to prevent the migration of material from the portion of the sheet under one opening to a portion of the sheet under another opening.

6. The slide of claim 5 in which said plurality of openings consists of a pair of adjacent openings.

7. The slide of claim 1 in which the sheet means comprises a separate sheet under each opening.

8. The slide of claim 7 in which at least one of the separate sheets has a reagent different from the reagent on another of the separate sheets.

9. The slide of claim 7 in which each sheet has barrier means to prevent material from passing from the sheet in the direction of an adjacent sheet.

10. The slide of claim 9 in which the plurality of openings consists of a pair of adjacent openings.
