DIRECTED-FLOW ASSAY DEVICE

摘要

A diagnostic assay device that directs an applied sample to the analytical membrane of a directed flow device. The device has a sample receiving port defined by layers of built-up material on one end of the test strip. The port contains the sample and specifically directs it to the membrane in a controlled fashion. Additional features include configuration of the housing in a general C-shape with the test strip spanning the opening of the C-shape to allow access by a reader device. A preferred method employs superparamagnetic particles to label the target analytes for detection and measurement by means of an electromagnetic reader device.
