Eligibility Criteria

Age18 Years - 65 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Adult military personnel (18-65y) will be included. Soldiers with and without previous exposure to allergens in the regions of interest will be included. Soldiers who are performing desk tasks and not selected for international missions will serve as controls.

You may not qualify if:

  • Skin pathology like chronic or exuberant urticaria, dermographism, chronic dermatitis that needs daily treatment
  • Use of antihistaminic medication \< 7 days before the start of the study
  • Use of tricyclic antidepressants (antihistamine activity) \< 7 days before the start of the study
  • Use of topical corticoids on the forearm \< 7 days before the start of the study
  • Use of Omalizumab \< 6 months before the start of the study
  • Pregnancy: there is a remote possibility of inducing a systemic allergic reaction that could induce uterine contractions or necessitate the use of epinephrine (thought to cause constriction of the umbilical artery).
