Assay device including a capsule, and housed within the capsule an assay insert made up of a filter unit, a conjugate reagent pad and a reaction membrane. The capsule has an opening covered by a capsule which is dissolvable by an external fluid containing an analyte. A porous filter unit occludes the opening in the capsule, providing for fluid communication of the analyte in the external fluid into the capsule when the capsule cap dissolves. The conjugate reagent pad housed in the capsule in fluid communication with the filter unit includes a mobilizable ligand with a label. The mobilizable ligand is capable of binding to the analyte to form a labelled, mobile ligand-analyte complex. A reaction membrane includes an immobilized detection reagent capable of binding the mobile ligand-analyte complex. The binding of the mobile ligand-analyte complex to the reaction membrane renders the label detectable on the membrane.
