LATERAL FLOW IMMUNOASSAY DEVICE WITH SEPARATION MEMBRANE

Abstract:

Lateral flow assay devices, systems, and methods described herein separate components of a fluid sample, including small volume, undiluted, unprocessed samples. In one aspect, components are retained in a separation membrane that is spatially above and in fluid communication with a conjugate pad of a lateral flow assay. Devices, systems, and methods described herein can retain particles from a fluid sample that obstruct flow of the fluid sample through the conjugate pad to a detection zone and/or interfere with detection of an analyte of interest in the detection zone.
