Add-on Testing Procedure. a Layout of the core laboratory prior to the automated specimen archival/retrieval unit. Add-on orders generate a print-out in the core laboratory with the testing information and patient demographics (1). A laboratory assistant reviews the print-out. If an add-on can be performed, the assistant prints an additional label with test information to a designated area of the laboratory (e.g., chemistry, 2a, or hematology, 2b) depending on the add-on order. A technologist enters in accession number into the computer program that tracks the archival rack and position for the specimen. Then technologist retrieves the specimen from the archival rack (3a or 3b) or from the refrigerator. The technologist loads specimen on proper analyzer (4a, 4b). b Layout of the core laboratory after the automated specimen archival/retrieval unit. Similar to above, add-on orders generate a print-out in the core laboratory that is reviewed by laboratory assistant (1). If an add-on can be performed, the assistant then uses a computer program to request the specimen be retrieved from the archiver (1). The archiver then locates the specimen and dispenses it (2). The assistant retrieves the specimen from archiver and loads specimen on to proper analyzer (3a or 3b)
