<p>A method and apparatus for inventorying frozen laboratory speciments (25) used in a hospital or research center includes placing the specimen (25) at a primary location behind a particular freezer door (15), selecting an 'identifier' (55) unique to that speciment (25) and displaying a symbol representing the primary location. As the number of specimens increases, secondary, tertiary and sub-tertiary locations will be displayed. Secondary location may be a rack (19) behind the door (15) and tertiary location may be a box (21) on the rack (19). Removing the specimen (25) from the compartment (17) involves manipulating the freezer interface device, e.g., keypad (43) and screen (39), to display at least the primary location. The user may manipulate by 'scrolling' the screen (39) or by entering certain specimen-identifying parameters such as a specimen description and date of storage. An optional security arrangement requires the persons that place and/or remove the specimen to enter a personal identification number (PIN).</p> |
