Histo-PinTAG™ labels represent an innovation in identifying and processing diagnostic microscope slides that require new or supplementary information. Typical microscope slides are processed with labels containing information related to the histology/cytology sample with the originating patient information. However, slides are often sent to consulting facilities that must re-process the information to ensure compatibility with digital scanners and databases. Histo-PinTAG labels are specially designed to cover existing 2D barcodes while, at the same time, adding new information that allows the proper recording of data via a new unique barcode.
