ABSTRACT:
The present invention relates to a self-contained assay device which is capable of detecting various analyte(s), including bioanalytes, in specimens for example, from biological sources. The assay device includes a first housing and a specimen holder rotatably fit in the first housing. The specimen holder has a center portion, a circular flange surrounding the center portion and a pin member extending from the underneath of the center portion. The center portion has a radial slot extending from its peripheral end toward a closed end. A spring/latch assembly is adapted to be held in the slot on the specimen holder and includes a spring member disposed in the slot near its closed end, a latch member having a remote end and a plurality of plunger members. The assay device also includes a second housing, preferably a cam-plate fixedly fit in the first housing. The cam-plate has a rim portion surrounding a concave portion adapted to accommodate the center portion of the specimen holder and an opening on the rim portion for adding a specimen to be tested. When the specimen holder is rotated relative to the cam-plate, the remote end of the latch member moves along the rim portion and thrusts into each chamber to drive the plunger member to release a reagent (or wash solution) for testing an analyte(s) in a specimen.
