Abstract:

A method and apparatus for testing tissue samples is provided which includes an integrated specimen test card. The test card is especially useful in testing for the presence of blood in stool samples and includes a frangible ampule contained within a channel mounted on the test card, the ampule containing a developer and the test slide being impregnated with a chromatographic reagent. Upon crushing the ampule within the channel, the developer is directed along a canal to a test section of the slide where, upon diffusion of the developer through the slide and moistening of the test slide by the developer in the presence of blood, a chromatographic reaction occurs to indicate to the user the presence of blood. A discrete control section having a second slide impregnated with reagent and a control indicator, such as hemoglobin, may be provided so that developing liquid can be directed simultaneously both to the test section of the slide and the control section of the slide.
