Abstract

The disclosure is directed to a method and apparatus for depositing a plurality of discrete liquid assay test samples onto an absorbent assay support. Pursuant to the invention, a guide and positioning device is provided to receive and position a device for dispensing a plurality of discrete test samples such that the dispensing device is operable to dispense the plurality of test samples in accordance with a predetermined pattern. A planar absorbent assay support device is positioned at a position which is vertically spaced and aligned below the guide and positioning device to receive the discrete test samples dispensed by the dispensing device. In this manner, a plurality of discrete test sample spots may be rapidly absorbed onto the absorbent assay support device in accordance with the predetermined pattern for efficient, simultaneous processing in a chosen immunoassay system.
