A lateral flow device includes a sample compressor and a test strip comprising a diverting zone. The diverting zone, which may include a barrier and/or a gap or ditch, stops or impedes flow. Flow is reinitiated and diverted into an alternate plane by compression of a sample compressor. Flow returns to the original, lateral plane, at the end of the diverting zone.
