Devices for analyte assays with built-in result reporting using recognizable symbols

A device for performing an assay to detect the presence or absence of an analyte in a sample comprising:

• a matrix that supports the flow of a liquid sample;
• an application zone on the matrix for receiving the liquid sample;
• one or more reagent zones on the matrix comprising reagents for conducting the assay;
• a detection zone on the matrix, the detection zone comprising
• an analyte binding area and a positive control area demarcated on the matrix;
• wherein the analyte binding area and the positive control area interact to form recognizable symbols indicative of the presence or absence of analyte in the sample, and
• wherein at least a portion of detection zone is covered by an opaque, movable material, wherein the opaque, movable material comprises beads.

A kit comprising:

• a device for performing an assay to detect the presence or absence of an analyte in a sample comprising:

• an application zone on the matrix for receiving the liquid sample;
• one or more reagent zones on the matrix comprising reagents for conducting the assay;
• a detection zone on the matrix, the detection zone comprising
• an analyte binding area and a positive control area demarcated on the matrix;
• wherein the analyte binding area and the positive control area interact to form recognizable symbols indicative of the presence or absence of analyte in the sample, and
• wherein at least a portion of detection zone is covered by an opaque, water-soluble dye;
• and
• instructions for use of the device.
