Methods and systems for authenticating goods using analyte encoded security fluids

A method for product authentication, the method comprising:

• a) applying an analyte encoded security fluid to a substrate of the product;
• b) obtaining a sample of the fluid from the substrate;
• c) testing the sample for the presence of the analyte using a test device comprising a test device code and a test strip, the test strip comprising an array of capture reagents positioned at different regions of a detection zone to form a capture pattern, wherein the test device code associates the test device with the capture pattern;
• and
• d) analyzing test results using an electronic device communicatively connected to an authentication authority, wherein the electronic device transmits the test device code and the test results to the authentication authority and in return is notified of authenticity after comparison to an authentication database of authentic test results, wherein:
• i) the test results are manually inputted into the electronic device corresponding to a viewed array pattern, or
• ii) the test results are uploaded to the authentication authority as an image file formed by the electronic device.
