ABSTRACT:
A self-contained system for testing for the presence of occult blood in a specimen has been provided with features enhancing its ease of use. The system includes a housing holding a test matrix and a container for releasing a developing medium onto the test matrix. The housing includes a base portion encasing both the container and the test matrix, and a moveable cover for selectively covering and uncovering the base. The cover is provided with a tab which can be manipulated with a finger of one hand, and the base is provided with tabs which can be grasped easily with one or two other fingers of the same hand, thus allowing the cover to be easily opened and closed with one hand. Other ease-of-use features include an applicator with a tip configured for optimized retrieval and even spreading of the specimen on the test matrix, and indicia imprinted at various positions on the housing designating both the location and order in which the different steps of the testing procedure are to be performed.
