description: This extension applies to the ServiceRequest resource and is used to represent the integer assigned to an individual test or service in a ServiceRequest that corresponds with the sequential position in which a test or service appears on a paper request form.\n\nSorting by display sequence enables more efficient reconciliation of paper and digital request data at the point of service provision.
