A device for determining presence or absence of infection due to an infectious agent is described. The device comprises a sample receiving zone configured to receive a liquid sample from a subject suspected of having an infection due to an infectious agent, the sample receiving zone positioned to distribute the sample along a first fluid flow path to a first label zone and along a second fluid flow path to a second label zone. Test lines in each fluid flow path capture a mobile detectable species as an indicator of presence or absence of the infectious agent. The device also comprises a reference line positioned in the one of the fluid flow paths. The bidirectional fluid flow paths emanate from a common sample zone and provide an efficient approach to detection and differentiate two species as indicators of the same infectious agent or as indicators of two different infectious agents.
