Abstract

A testing device for determining the presence of occult blood in fecal matter has a primary support sheet with several window openings therein for receiving fecal matter. Guaiac test paper positioned on top of the support sheet covers the window openings. A strip of flexible opaque material is folded in two over the test paper, and a portion of the flexible material forms a pull tab which extends outwardly and away from the support sheet. An absorbent pad impregnated with hydrogen peroxide/alcohol is secured on top of the layered strip material, and a seal wrap covers the layers of strip material and the absorbent pad. Pulling the tab away from the primary support sheet draws the absorbent pad under the layers of flexible material and across the test paper to thereby moisten the paper covering the window openings and react with the guaiac in the test paper to turn the paper blue when blood is present in the fecal matter.
