On the next page of the site you are presented with a list of 5-10 differential diagnoses. You can drag and drop to prioritise these. You must save this initial prioritisation before proceeding, although you can return to amend it at any time prior to finalising your test ordering. Note that if you do not use one or more of the possible diagnoses, these will not be available when you finalise your diagnoses towards the end of the case study.
