A method and slide for collecting and testing fecal occult blood which permits multiple analyses of a single fecal sample. The slide contains a pocket-like member on a portion of the inside front cover of the slide. An absorbent insert is disposed in the pocket. When the cover is in a closed position the pocket overlies the fecal smear on the specimen viewing sheet and the insert can be removed from the pocket. This design permits an analysis to be done on the specimen receiving sheet of the slide together with a second confirmatory test on the insert.
