Abstract: A system and method for handling laboratory information includes a graphical user interface with a plurality of windows. A palette of icons is provided in a first one of the windows, each icon representing a predetermined task to be executed by a processor in communication with the graphical user interface. The processor is also in communication with a database containing static laboratory data (such as the type of sample to be analysed) as well as dynamic laboratory data (such as the name of the specific sample to be tested and the results of that test). A user can select icons from the first window and “drag and drop” them into a second window. A sequence of tasks may thus be built up, in the form of a tree structure, and when run the processor executes the sequence of tasks in turn by reference to the static and dynamic laboratory data.
