Accuracy array assay system and method
First Claim
1. A device for detection of targets comprising an array of at least 4 spaced apart detection zones, each detection zone containing at least 6 spaced apart detection spots in a pre-determined pattern, the detection spots being suitable for providing a detectible indication of the presence of a specific target, there being at least 3 different detection spots in each detection zone, wherein no two detection zones have the same pre-determined pattern.

Abstract
An array device for detection of targets has a plurality of detection zones containing different detection spots in a predetermined pattern, such as edge effects. The detection spots are randomized to reduce inaccuracies resulting from spatial effects. Preferably, no two detection zones have the same pre-determined pattern. The device can be provided with a readable code to allow a detector to determine the predetermined pattern used for the array.
