Will update sending and receiving systems' definitions to clarify. Sending systems are defined as systems that generate and push data within a pathology lab workflow. These systems may be used by clinicians (ie Oncologists) when ordering the pathological analysis for a patient, which will necessarily entail the collection (procedure) of said specimen, and sending of this specimen to a lab. These systems may also be use by Pathologists in cases of completed analysis and reports that need to be sent back to an clinician and/or to a cancer registry.  Receiving systems are defined as systems that receive and are expected to process data within a pathology lab workflow. These systems may be used by Pathologists (ie LIS, associated interface engines) when receiving a specimen and a request for analysis. These systems may also be used by Clinicians who ordered the lab analysis/report. Also,these systems may represent central registries who aggregate and analyze pathology lab information.
