A method of assigning an additional test to an existing aliquot sample tube or to a primary sample tube in a laboratory automation system is presented. The laboratory automation system comprises a workflow control unit and analytical laboratory devices in communication with the workflow control unit. The method comprises receiving an additional test request for the existing aliquot sample tube after processing of the existing aliquot sample tube has started, determining if the existing aliquot sample tube is at a retrievable target, waiting until the existing aliquot sample tube reaches a retrievable target if not at a retrievable target, determining if an aliquot timeout has occurred once the existing aliquot sample tube is at a retrievable target, reassigning the addition test to the primary sample tube if an aliquot timeout has occurred, and performing the additional test from the existing aliquot sample tube if no aliquot timeout has occurred.
