Abstract
Lateral flow assay devices and methods for detecting an analyte in a sample which comprises a plurality of nonspecific binding pair members are adapted for two step determinations. In one embodiment, a method for identifying IgE antibodies in a sample comprises applying a sample to a sample port of a device, wherein the device is adapted to deliver the sample to a lateral flow matrix having a plurality of IgE antigen species immobilized at respective positions at a first location, allowing the sample to travel along the lateral flow matrix through the immobilized plurality of IgE antigen species to a second location downstream of the first location and allowing sample to dissolve a water-soluble mark, applying liquid buffer to the lateral flow matrix to mobilize labeled reagent which is adapted to bind anti-IgE antibody and which is dried on the lateral flow matrix at a location upstream of the sample delivery location, and allowing labeled reagent to bind any IgE antibody bound to the immobilized IgE antigen species therein.
