Abstract: A system and method for lateral flow assays, utilizing a test strip having at least three sections, where the second section contains multiple test lines arranged at an angle to the direction of flow, each test line configured to capture at least one conjugated rare earth particle bound to an analyte of interest, where the test strip is configured to be read in a direction perpendicular to the direction of flow.

Abstract: A lateral flow test strip for the analysis of a sample featuring numerous capture zones arranged in an array such that each capture zone is substantially equidistant from the sample containing area. The sample does not pass through another capture zone to reach any one of the other capture zones. The capture zones are preferably arranged in a linear array perpendicular to the flow of the sample through the lateral flow test strip. The lateral flow test strip allows for an increased number of simultaneous analyses of numerous analytes from one sample to occur on one lateral flow test strip.
