Abstract:
The present invention provides devices, methods and kits for detecting the presence of an analyte in a liquid sample. The invention provides devices having a positive control area covered with an opaque, movable material, such as an ink, dye, or other material, that is moved on the device by the flow of liquid sample, thereby exposing the positive control area underneath. Using the interaction of colored signals from the positive control area and the analyte binding area, a recognizable symbol is revealed on the device that correlates with the test results, and appears as the test is conducted.
