Bring any previous results

If you were diagnosed abroad, bring a laboratory report or discharge letter where possible. Tell the clinician if the diagnosis was based only on symptoms or if the result is unavailable.

Review the full itinerary

Share your destinations, departure date, duration and whether you expect repeated trips. Ask how this information and your medical history affect suitability and whether the timing is practical.
