A method for detecting and identifying nucleic acid tags. A nucleic acid tag comprising a nucleotide-support platform attached to a nucleic acid molecule is created or selected and then immobilized on or in an item, or seeded within an area of interest. Samples are obtained from the surface of an item that has potentially been labeled, and an initial screen is conducted using universal primers to determine which samples contain nucleic acid tag. A multiplex screen is conducted on samples testing positive for nucleic acid tag in order to identify which of a plurality of nucleic acid tags are present on or in the item of interest. |
