20. The method of claim 17 , wherein the uniquely identified molecular entity is a specific human gene.
17. A method, which is implemented using a computing device, of identifying a test component that is usable to perform an orderable healthcare procedure, the method comprising: receiving as an input the orderable healthcare procedure, wherein the orderable healthcare procedure is associated with a particular molecular entity; displaying on a display device a navigational concept that represents a parent tier in an ontology hierarchy; responsive to input of the navigational concept, identifying by a processor a uniquely identified molecular entity that relates to the particular molecular entity and that is a child concept of the navigational concept; traversing biological relationships of the uniquely identified molecular entity to identify by the processor a potential test component of a task, which is executed to carry-out the orderable healthcare procedure; displaying the potential test component to enable selection thereof; and upon receiving input of the potential test component, displaying the potential test component as the test component of the task.
