Abstract
An improved test device, useful in conducting reactions, which comprises (a) a well lconfigured to confine temporarily a liquid patient sample admixed with at least one reagent, such as an immunoreagent, to conduct such a reaction, (b) a filter at the bottom of the well with pores effective to pass free, unreacted reagent but not reacted or complexed reagent, and (c) an absorbent material underneath the filter effective to draw off liquid in the well after the reaction. The device further includes (d) a non-absorbent pad underneath the filter, adjacent to the absorbent material, and (e) means for moving the filter and the absorbent material relative to each other, and the filter and the pad relative to each other, between two positions, one in which the filter contacts the non-absorbent pad and the other in which the filter contacts the absorbent material.
