Abstract

An immunochemical assay device comprising a base member, an array disposed on the base member, and at least one assay indicia zone. The array comprises (i) a reservoir pad to receive sample liquid, (ii) a wicking membrane, and (iii) at least one filter zone interposed between the wicking membrane and the reservoir pad. The filter zone being operable to permit passage of any specific immunocomplex to the wicking membrane while impeding passage of larger components.

Independent Claims | See all claims (2)

  1. 1. An immunochemical assay device comprising:a base member;an array disposed on said base member, said array comprising:(i) a reservoir pad having sufficient porosity and volume to receive and contain a liquid sample on which the assay is to be performed;(ii) a wicking membrane disposed distally to said reservoir pad, said wicking membrane having sufficient porosity and volume to absorb a substantial proportion of the sample received in said reservoir pad; and(iii) at least one filter zone which is separate and distinct from said reservoir pad and wicking membrane, and interposed between and contiguous with said wicking membrane and said reservoir pad, said filter zone having impregnated therein a labelled immunochemical component capable of binding to an analyte of interest in said sample to form an immuno-complex, said filter zone being operable to permit passage of any specific immuno-complex to said wicking membrane while impeding passage of larger components then contained in said sample; andat least one additional immobilized immunochemical component disposed in at least one assay indicia zone of said wicking membrane downstream of said reservoir pad and defining assay indicia.
