Allergy Patch Testing in Phoenix, Arizona

What You Need to Know About Patch Testing & Patch Testing Costs

Patch testing is the only medical test that can identify a delayed allergy. Unlike “immediate” allergies like you hear about to peanuts, pollens, and dog dander, “delayed” allergies to things like perfumes or other ingredients in cosmetics can cause a form of eczema over time. A patch test may include between 36 to 85 allergens. In some complex cases, expect over 100 allergens. In addition to paying for 2 or 3 office visits, the patch test allergens often cost $9. An average test may cost around $1000 but often patients pay much less out of pocket. Experts agree that for many patients with out of control eczema and rashes, patch testing is very likely to save you time, money, and trouble in the long-run.

The allergic form of eczema is often a life-long disease. While this test seems very expensive, it is much less than the total costs of monthly prescriptions, specialist visits several times yearly, and loss of work or vacation time. Without a proper diagnosis, patients may suffer needlessly or even pay for unnecessary treatments for decades. The other problem is that patients can become allergic to many of the creams used to treat eczema. If you have eczema that can’t be controlled, you deserve to know if you could be allergic to the ingredients in your prescription and over-the-counter eczema creams. The team at Saguaro Dermatology invite you schedule an appointment to learn more. And being centrally located in Phoenix, you will experience convenience and efficient care.

Q & A: Prior to undergoing patch testing, there are several questions you should ask your physician and/or your insurance provider.

Generally, the procedure is covered by insurance plans, or it may require a prior authorization.

This is an important question because some insurance plans will only cover a limited series.

Some clinics associated with a hospital system may charge a “facility fee” which can more than double the cost of the test. If there are no other experts in your area, you may have no choice, but this question may help avoid surprise bills. Saguaro Dermatology does not charge a facility fee.
