The device is a composite strip comprising at least two bodies (200 and 201) of porous liquid-conductive material in flow contact with each other via an interface (205) and defining at least part of a liquid flow path through which liquid flows during the assay, wherein at said interface the lateral dimension (207) relative to the direction of the liquid flow path, of the contact area of the upstream body is narrowed such that liquid flow from the upstream body into the downstream body is towards the centre-line of the flow path in the downstream body, thereby reducing the likelihood that liquid will deviate from the intended flow path. The upstream body can be a sample-collecting wick, terminating at the interface as a point or prow. Utility is in determining analyte presence in urine using binding regents and immunoassay procedures. |
