Abstract
Test strip devices, assemblies, systems, and methods for the analysis of a sample are shown and described. In one embodiment, a test strip includes a membrane, a filtration conjugate pad with a fibrous labeled receptor bottom side, and an overlay tape enclosing the membrane and a portion of the filtration conjugate pad. An assembly may include a delivery device for delivering sample to the test strip.
Claims16
A lateral flow test strip for the analysis of a sample, said test strip comprising:
- a. a backing support;
- b. a membrane adhered to said backing support and including at least one control area and at least one test area;
- c. a filtration conjugate pad having a top side and a fibrous bottom side and aligned to said membrane at a contact point, and wherein said bottom fibrous side includes a labeled receptor, and wherein said contact point includes at least about a millimeter of an overlap of said filtration conjugate pad onto said membrane;
- and
- d. an overlay enclosing said membrane and said contact point between said membrane and filtration conjugate pad.
A lateral flow device for the analysis of a sample comprising a test strip having a membrane, a filtration conjugate pad having a contact point of at least about a millimeter of overlap about said membrane and including a fibrous bottom side with a sprayed bead labeled receptor, and an overlay tape enclosing said membrane and a portion of said filtration conjugate pad.
