This function exists so you can pose further questions and request clarification on reports that have already been approved. This feature is free of charge as any addendums are included in the original report fee. To do this, you can simply type your question in the Addendums box on the report, and then click Submit Addendum Questions.
This request is then made available for Dr Makdissi to view and respond to. When this process is complete, you will, like when a report has been approved, receive an email notification asking you to log in to view the Addendum response.
