Allergy skin testing identifies specific inhalant
and food allergy triggers. Patients are taught how to properly use medication to
prevent or treat allergic diseases, monitor the efficacy of their treatment
regimen, and are instructed in appropriate environmental control measures for
indoor and outdoor allergens.
Specific allergen vaccine immunotherapy
may be recommended for those patients suffering from seasonal or perennial
allergy and/or asthma symptoms caused by allergens that they cannot avoid or
that are not completely controlled by medication. Allergy vaccine therapy
modifies the body's immune responses to offending inhaled allergens, resulting
in decreased allergic inflammation. The decreasing allergic inflammation
ultimately leads to less nasal, sinus, and bronchial congestion, less secondary
infections, less need for medication, and an improved quality of life in the
home, at school, at work, and out of
doors.
Because of the
nature of allergy consultation and testing, there is a great deal of information
that is covered during the visit. You should make arrangements to be in our
office for approximately two hours. Please do not bring other young children,
but if you must, bring another adult to provide proper supervision so that you
may give your full attention to the Doctor and the information given. If for any
reason you are unable to keep your appointment please contact our office as soon
as possible, at least 48 hours in advance, so that appointment time may be given
to another patient. Please do not plan on making or receiving cell phone calls
during your appointment.
MEDICATIONS PRIOR TO SKIN TESTING:
Please
do not take any antihistamines prior to allergy skin testing. These include any
medications you may be taking for allergic nasal, eye, or skin symptoms. Certain
anti-depressant, tranquilizer, and stomach medications can also interfere with
skin testing. Please report ALL medications you or your child are taking prior
to skin testing. Benadryl, diphenhydramine, Chlortrimeton, Dimetapp, Tavist, and
other antihistamines must be stopped two (2) days before skin testing. Some
other antihistamines such as Claritin, Clarinex, Xyzal, Astelin, Astepro,
Allegra, Zyrtec, Dallergy, and hydroxyzine, fexofenadine, loratidine,
cetirizine, and Atarax must be stopped four (4) days prior to testing. ASTHMA
MEDICATIONS SHOULD NOT BE DISCONTINUED. Please review these medications with us
as well.
No Beta-Blocker medications are permitted for 24 hours prior to
skin testing. These medications are commonly used for heart disease, glaucoma,
hypertension, arrhythmia, and migraine headaches. If you are on a Beta-Blocker,
please take the last dose 24 hours prior to your appointment. On the day of the
testing, bring your Beta-Blocker medication with you so that you may take that
day's dose immediately after the testing. Make sure our office knows you are on
a Beta-Blocker when scheduling.
ALLERGY CONSULTATION AND
TESTING:
The initial allergy consultation will include a detailed
history, physical examination, and if scheduled, inhalant allergy skin testing.
Food allergy testing is performed during the second (summary conference) visit.
Very young children may receive a lesser number of tests, with both the inhalant
and food testing perfomed at the same visit. Skin testing is performed by gently
pricking the surface of the skin on the back with a Derma-Pick. The Derma-Pick
is a small plastic rod with tiny tines that contain a droplet of allergen that
is brought into contact with allergically reactive cells called mast cells in
the superficial layer of the skin. If one is allergic to that allergen, the mast
cells release histamine which causes an itchy hive to form at the pricked site.
The test is read 20 minutes after the application and indicates those allergens
to which one is allergic and to what degree. Derma-Pick is the most
technologically advanced method of testing and is very minimally and briefly
discomforting. Small children are tested in the parents lap. Once the tests are
applied (usually in less than 1-2 minutes), children usually relax and are free
to move around and play with toys provided. Intradermal testing, similar to a TB
test, may be required to check for those important allergens that did not show
up on Derma-Pick testing. These tests are read 10 minutes after application. The
discomfort level with intradermal testing is usually less than or equal to
Derma-Pick testing. Skin testing is the most accurate and appropriate method
that is commonly used to determine specific allergic sensitivities to pollen,
dust/dust mite, mold, animal, food, drug, and stinging insect allergens.
If there are local reactions from the skin testing, they usually fade
away within minutes to few hours. If stronger reactions occur, an antihistamine
may be given after the testing to relieve the itching.
Computerized pulmonary function testing will be
performed on all school-age children and adults with known or suspected
asthma. |
