description: This extension applies to the AU eRequesting Diagnostic Request profile and any derived ServiceRequest profiles. The display sequence is an integer assigned to an individual test or service in a ServiceRequest that matches the sequence as seen on a paper request form. The ability to sort on sequenceNumber more easily allows for reconciliation of paper and digital requesting data by the filler, especially for collection centre staff within a pathology collection centre.
