An assay test strip and cassette. The test strip is positioned in a housing shaped and configured to allow a detector to access the test strip from the side, rather than from the lengthwise axis of the test strip. The housing may contain one or more test strips which may also be disposed on one or more surfaces of the housing. Preferably, the housing is generally C-shaped with the test strip spanning the space between the two arms of the C-shape. The housing is sealed to protect both the operator and instrument from possible contamination. The test strip is preferably embedded with paramagnetic particles and process chemistry specific for a particular application. Quantitative analysis may be accomplished using a magnetic reader device. In additional embodiments, detection is accomplished by visual means.
