Additional information

  Donating before or after travel should not be a problem, provided the donor is well hydrated. Travelling, particularly by plane, can be dehydrating and this may increase the risk of developing a thrombosis. If the donor is dehydrated, they should be advised to delay donating until they are well hydrated to avoid an increased risk of fainting.

  If the donor is likely to be exercising in conditions where the amount of available oxygen is low (e.g. at high altitude), it may be sensible to delay donation within 2 weeks of travel to avoid the possibility of increasing the risk of adverse events.

Reason for change:
  The See if Relevant section has been revised.
