description: This profile defines the minimum expectations for representing display sequence in the AU eRequesting context.  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 based on display sequence more easily allows for reconciliation of paper and digital requesting data by the filler, especially for collection centre staff within a pathology collection centre.
