MULTIPLANAR LATERAL FLOW ASSAY WITH SAMPLE COMPRESSOR

摘要

A sample compressor applies pressure to a sample collector and a sample application zone of a test strip to transfer a sample from the sample collector and a binding partner of an analyte to the sample application zone in a lateral flow device. At least one of the binding partners of the analyte is not located on the test strip prior to use of the lateral flow device. The test strip may be a universal test strip with no molecule that specifically binds the analyte is located on the test strip. The sample compressor may be a universal sample compressor also with no molecule that specifically binds the analyte on the sample compressor. The lateral flow device may also include one or more enhancement elements, where the enhancement elements bind to the analyte sandwich to increase a detection signal in the test zone.
