A wick for use in determining sufficiency of an amount of analyte fluid provided to an analyte test section of an assay device is provided. The wick comprises a primary wick portion attached or attachable to the analyte test section so as to be in fluid communication therewith. The primary wick portion has a receiving surface adapted for receiving the analyte fluid and is configured to draw the analyte fluid from a first area to a second area of the primary wick portion. The assay wick further comprises an indicator portion having a contrasting visual characteristic. The indicator surface is covered by at least a portion of the primary wick portion, which comprises a wicking material that becomes more light transmissive when wetted by the analyte fluid. The contrasting visual characteristic is viewable through the at least a portion of the primary wick portion only when the at least a portion of the primary wick portion is suffused by the analyte fluid.

Bonded fiber matrix containing encapsulation complex

A bicomponent fiber wick is provided for use in processing an analyte fluid. The bicomponent fiber wick comprises a self-sustaining, fluid transmissive body comprising a plurality of bundled, crimped, bicomponent fibers bonded to each other at spaced apart contact points. Each bicomponent fiber has a fiber structure comprising a first fiber component formed from a polyamide material and a second fiber component. The fibers collectively define tortuous fluid flow paths through the fluid transmissive body, the fiber structure being configured for controlling flow of the analyte fluid through the fluid transmissive body with at least a portion of the first fiber component in contact with the analyte fluid.
