A Lateral Flow test device, a test Apparatus to monitor the specific Weight of a urine Sample comprising Said device, Said Device comprising an Absorbent article and a method for Controlling the lateral flow

摘要

We describe several modifications to a porous substrate, as used in lateral flow test Devices, to adjust or modify the pattern of flow rate and / or the path of flow of a Fluid through the Porous substrate.The lateral flow Assay device has a Matrix of Porous substrate in Fluid communication with a control area flow rate with a number of control devices arranged as Flow Rate characteristics in or on a surface of the substrate or rolled my Mo, in a body.The Flow Rate Control devices may include: a Density Gradient, a gradient of Porosity gradient Affinity, Ion, micro channel, and combinations thereof.
