with a CD10 stain). Given that information, the ability to communicate with the originating laboratory becomes possible. To ensure the success of this proposed unique ID standard, this unique ID must be considered a separate entity from what is currently used in laboratories today with respect to the human readable identifier in place now. Two reasons drive this separation. First, the physical space requirements present with some of the derived specimen types in anatomic pathology restrict the amount of information that can be present in the human readable part of the label. This is clearly seen in the labeling done for cassettes and slides, where the available area for a label is small given the size of the item. Another reason for the clear separation is the potential length of the unique ID so that the laboratory sub-identifier can be long enough to handle the current and future number of laboratories globally. Unique ID Technical Schema Workflow and Physical Requirements The standard must enable the creation of a globally unique identifier for both specimens and containers. The standard must be able to handle the relationship between specimens and containers. As stated in the glossary, every specimen is held by a container. From the perspective of the specimen, this is a one-to-one relationship. While the current majority of containers contain a single specimen, the relationship from the perspective of the container is a one-to-many. There are a growing number of scenarios in which a single container houses a number of separate, unique specimens. the one-to-many nature of the container-specimen relationship, the standard will place the unique container ID in the machine-readable component of the label. This design will allow for efficient and scalable lookup of specimens held within the container. This standard will allow for a distinct detection of a machine-readable ID in keeping with the standard to prevent mis-interpretation with a currently implemented schema in use. The length of these IDs will be amenable to current LIS storage and implementation abilities and the available technology for identification Information Requirements Location ID This is the origin of the specimen, such as the laboratory where it was accessioned. – This will be contained as a prefix in the specimen and container IDs. Specimen ID– The alphanumeric sequence that uniquely identifies the specimen for the given location. Container ID The alphanumeric sequence that uniquely identifies the container. –
