Abstract: A test device and method for determining the presence or absence of one or more analytes in a fluid sample, the test device including a support or member bearing a mark thereon, and a matrix or member containing a capture zone.

Typically, the mark on the underlying support is configured as a minus (?) sign. In the absence of analyte in the sample, the test device presents a negative result as a minus (?) signal. In the presence of analyte in the sample, however, the mark operates in concert with a perpendicular test line on the observation area to present a positive result as a plus (+) signal that is visible to the user.
