MULTIPLE-CHANNEL TEST DEVICE, METHOD FOR PRODUCING THE SAME AND USE THEREOF

摘要

The object of the invention is a multiple-channel test devise based on immunodiffusion and immunochromatography, which enables the simultaneous or parallel determination of several analytes. In the test devise, it is possible to group together different combinations of markers recognizing allergens, myocardial infarction markers, venereal disease analytes, blood screening analytes, respiratory infection producing agents, IgG, IgA and IgM antibodies, other infectious disease producing agents as well as various cancer markers. The multiple-channel test devise comprises a porous carrier material on which a channel network has been formed by etching the carrier material by laser to form a shaped figure that contains several channels. In the channels, various specific binding reagents have been immobilized, which enable the diagnoses of a target illness and/or syndrome. The sample application point is optionally provided with a filter and optionally contains a label mobilizable by the analyzable sample and a specific binding reagent. Also the method for the production of the test device and its use are disclosed in the invention.
