Abstract

A combined sample-assay device allows sampling and detection within an integrated device. The device is a flat plate-like body with a collection arm. The collection arm optionally folds to enter a recess that flatly supports and seats the arm. The arm may be friction held in this recess and completely enters the recess. Within the recess is a second recess that contains a reading portion and transport portion. Chemiluminescent or other light emitting chemical reagent is placed within the device and light is detected in response to the presence of a sample analyte in a fluid sample.
