Patient Instruction & Consent Form

for Allergy Skin Testing

⏰ Important Appointment Reminders

Be on time for your skin test appointment. If you arrive late, we may be unable to test you due to the testing schedule.

Wear comfortable clothing. You will be asked to take your top off. Please do not wear a one-piece outfit.

Small children: We request that you do not bring small children with you when you are scheduled for skin testing unless they are accompanied by another adult who can sit with them in the reception room.

🚨 When to Reschedule

You will need to notify our staff if you have:

Call our office and we can reschedule your allergy testing.

📅 Cancellation Policy

Please do not cancel your appointment since the time set aside for your skin test is exclusively yours for which special allergens are prepared. If for any reason, you need to change your skin test appointment, please give us at least 48 hours' notice, due to the length of time scheduled for skin testing. Any last minute change results in a loss of valuable time that another patient might have utilized.

What is allergy prick skin testing?

Your doctor has suggested you/your child have this test as part of the evaluation at the office. Prick skin tests are done to help identify if you/your child are allergic and what you are allergic to.

Skin testing is a simple series of tiny scratches made on your back with an instrument that has small toothpick-like prongs each containing trace amounts of a single allergen. Your doctor determines the number of tests done according to the history you have given. Skin testing is not painful.

After skin prick testing some patients may also receive intradermal testing. With intradermal tests, a small amount of the allergen is injected under the skin of the arm to see if it causes a reaction.

⚠️ Important Medical Information

Skin testing will be administered at this medical facility with a medical physician or other health care professional present since occasionally reactions may require immediate therapy. These reactions may consist of any or all of the following symptoms:

Please note that these reactions rarely occur but in the event a reaction would occur, the staff is fully trained and emergency equipment is available.

Please let your physician and nurse know if you are pregnant or taking beta-blockers. Allergy skin testing may be postponed until after the pregnancy in the unlikely event of a reaction to the allergy testing and beta-blockers are medications that may make the treatment of the reaction to testing more difficult.

How long will the test take?

Prick skin testing often takes 60 to 90 minutes to complete.

What to know after the testing:

After skin testing, you will make an appointment to meet with your physician who will review your testing results and make further recommendations regarding your treatment.

There can be swelling or redness at the skin test sites, which can appear several hours after your testing, called "delayed reactions" and do not have any significance. Any itching associated with these reactions can be managed with steroid creams and antihistamines.

If possible print the consent form and bring it with you.
