9. A computerized system for identifying test components, which are usable to perform an orderable healthcare procedure, the system comprising a processor coupled to computer-storage media that comprises: a receiving component that receives an input of the orderable healthcare procedure, wherein the orderable healthcare procedure is associated with a particular molecular entity; an associating component that, upon input of a navigational concept, associates the orderable healthcare procedure with a discrete ontology concept, (1) wherein the navigational concept includes a category of molecular entities that is a parent concept of said discrete ontology concept, and (2) wherein the discrete ontology concept includes a uniquely identified molecular entity, a traversing component that traverses an ontology of the discrete ontology concept to identify test components related to the discrete ontology concept, wherein the ontology comprises horizontal defining biological relationships associating the discrete ontology concept with the test components; and a displaying component for displaying identified test components related to the discrete ontology concept.
16. The system of claim 9 , wherein the ontology is an ontology of genomic concepts.
