LFA Rapid Detection Test

Application ID: 99341

This example introduces three different models for a lateral flow assay for the detection of coronavirus antibodies.

These models are as follows:

  • 3D model for studying possible symmetries in the spreading of the liquid sample in the test strip.
  • The 3D model shows that the flow is essentially 2D.
  • Two 2D models are therefore defined in which the adsorption reactions in the test strip are assumed to be located at a) the surface of the test strip and b) distributed along the thickness of the porous layers of the conjugate pad and membrane.

This model example illustrates applications of this type that would nominally be built using the following products:
