Abstract

In a lateral flow test (LFT) device, the liquid conduit element 20 is formed from a substrate 21, 22 or 24 having at least two layers, including a first layer 21b, 22b or 24b not exceeding 75 μm in thickness formed from a porous material for wicking liquid, and a second layer 21a,22a or 24a of additional thickness formed from a generally non-porous polymer material acting as backing layer. The layered arrangement is incorporated into an LFT device to reduce sample volume requirements.
