| YOUR
APPOINTMENT: WHAT TO EXPECT
Antihistamines
must be avoided for the seven days preceding your appointment.
All of your other medications should be taken as prescribed.
An allergy
testing appointment can take as long as an hour, an hour and
a half if pulmonary function studies are done as well.
Please
arrive a few minutes early as you will need to complete an
allergy questionnaire or download the questionnaire here online (Word or PDF), fill and bring to the appointment. This will help the specialist determine
which allergens you should be tested for.
Allergy scratch test: Test done on the skin to identify the
allergy substance (the allergen) that is the trigger for an
allergic reaction.
A small amount of the suspected allergy-provoking substance
is placed on the skin. The skin is then gently scratched through
the small drop with a special sterile needle.
If the skin swells, then the test is read as positive and
allergy to that substance is considered probable.
