After you have reviewed the results of your first encounter, you will usually want to order additional investigations. If you return to the "Order tests" screen, those tests ordered in the previous encounter(s) will be highlighted in pale blue. Within a given case study in iNvestigate, individual investigations are deliberately not made available for ordering on more than one occasion.
If you proceed to the next tab you will be given the opportunity to return to ordering tests, or to finalise your test ordering. Only click the "Finalise" button if you have completed your test ordering and are ready to proceed.
When you have finished ordering and reviewing the results of investigations, you can proceed to the next tab to finalise your test ordering. You must do so after completing 5 test ordering encounters.
