What You Need to Know for Allergy Testing
Thank you for choosing our practice for your allergy needs. There are several methods of skin testing for allergies. Our practice uses the (MQT) Modified Quantitative Method. The skin of your forearm is pricked with a plastic device and depending on your response, we may do some intradermal injections in the upper arm. We will test for 29 different allergens including cat, dot, mite, molds and pollens. We do not do skin testing for food allergies, however, we can order a blood test for food allergies if the physician feels it is medically necessary.
Your skin test appointment generally takes 40-70 minutes depending on the results. We require that you wear a short sleeve or sleeveless shirt for your own comfort. For their safety and comfort, we ask that you leave infants and children with a caregiver. If you have asthma and have an inhaler, please bring it with you to your testing appointment.
Upon completion or your allergy test, we will apply Cortisone cream to your arms. If itching and redness continue, you may reapply Cortisone or Benadryl cream at home. If you have any delayed large reaction(s) on your arms, please call the office.
The following must be avoided prior to the testing appointment:
- Beta-blockers: These medications cannot be taken 5-7 days prior to skin test for safety reasons. Beta-blockers are often used to treat high blood pressure, glaucoma, or migraines. Please consult the physician who prescribed the medication prior to testing to see if discontinuance is permitted. Do not stop taking the beta-blocker without your prescribing physician’s approval.
- Antihistamines: Antihistamines such as Benadryl, Allegra, Astelin, Astepro, Patanase and Dymista must be stopped 3 days prior to skin test. Zyrtec, Claritin, and Clarinex must be stopped 1 week prior to the test. Singular, Xyflo and Accolate must be stopped 1 day before the skin test.

Also, the antidepressants Remeron and Seroquel can interfere. Please check with your prescribing doctor before stopping any of these medications.

Our experience has been that allergy testing is a covered benefit with most insurance companies. However, it is always a good idea to check with your insurance company to see how these tests are covered under your plan. The codes we use for testing are 95004 and 95024. Ask if these tests are a covered benefit and whether any co-pay, co-insurance or deductible will apply. You might also ask if there are any exclusions under your policy.
