Abstract
Apparatus for performing immunoassays which is essentially self-contained, requiring only the introduction of a sample and, at appropriate times, washing solution. The apparatus (10) includes: a fluid container (12) having a central platform area with a reaction area (30) which can contain a reactive agent; a sample receiving chamber (22) having a sample conduit (24) located above the porous medium; at least one openable reagent container (46); a conduit (28) for directing reagents onto the porous medium; an opening member (50) attached to the upper unit and positioned to contact and open reagent containers sequentially, by incremental relative rotation of the upper and base units; and a window (34) for viewing the reaction area. The apparatus can also include a sampler member (58) in the nature of a tampon for assays involving samples taken from body cavities.
