Laboratory Testing Workflow

Laboratory Testing Workflow (LTW) integrates the ordering, scheduling, processing, and result reporting activities associated with in vitro tests performed by clinical laboratories in healthcare institutions.

Summary

The Laboratory Testing Workflow Profile covers the workflow related to in vitro tests performed by a clinical laboratory inside a healthcare institution, for both identified and unidentified orders, related to both identified patients and unidentified or misidentified patients. It specifies transactions that maintain the consistency of patient and order information from registration through ordering, scheduling, pre-analytical processing, testing, technical and clinical validating, results reporting. This profile leverages IT Infrastructure profiles [PAM] or [PDQ] to rely on up to date patient and encounter data. This profile leverages IT Infrastructure profiles [ATNA] and [CT] for security.
