1. A computer storage medium having embodied thereon computer-readable instructions that, when executed by a computing device, enable the computing device to perform a method 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 device a navigational concept that represents a parent tier in an ontology hierarchy; responsive to input of the navigational concept, identifying 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 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 a test component of the task.
