About the painless allergy test

Is there an age limit for testing and treatment?
No. Small children will be tested for fewer antigens than older children and adults, but the test is safe for children of any age.
Can I be tested if I have a skin condition or moles?
Yes. If possible, your provider will place the test on areas that are not acutely affected. If there are no unaffected areas, you will receive a blood test instead of a skin test.
Can I be tested if I have a tattoo?
Yes. The technician will place the test on areas that are not inked. He or she may use ink-free areas on your back, arms, or legs. If you are inked in all areas, you will receive a blood test instead of a skin test.
How much does testing cost?
It is covered by most insurance plans. You will only be responsible for your regular co-pay and deductible. We also offer a significant testing price discount to cash pay patients at $199.00 for the test.
How long will it take for results to develop?
Results will be available in just 15 minutes. A Doctors Express technician will check on you every five minutes or so during that time to make sure you are okay. After 15 minutes, he or she will read the results and remove the antigens with an alcohol swab.
How long will the reaction last after testing?
If your body is allergic to certain antigens, you will get temporary, small bumps on your skin and you may feel a little itchiness. Both will begin to resolve as soon as the antigen is wiped away at the end of the test. Bumps usually last about an hour and in the majority of tests, the patient feels little if any discomfort.
How often will I get retested?
Once each year. Re-testing helps you and your provider evaluate your improvement. It is important, though, to understand that the skin test is just one measure in the assessment of progress toward remission.

About allergy treatment after a positive test

How does sublingual immunotherapy work?
Low doses of harmless allergens are placed under your tongue where they are absorbed by tiny capillaries. These allergens then attach to dendritic cells, which in turn affect your TH2 cells in ways that reduce and/or eliminate allergies and related symptoms.
How safe is sublingual immunotherapy?
Drops are extremely safe, with rare, and mild, side effects. There have been no fatalities reported. SLIT has been used for over 60 years worldwide and the majority of allergy patients in Central Europe receiving immunotherapy use SLIT.
How long do I stay on SLIT?
Three years. If you are unable to complete the treatment, the allergen resistance will last a few weeks or months after treatment is discontinued. You will be able to restart treatment at any time, but if several months have passed you may be advised to restart at the first stage of treatment.
Do the drops work on food allergies?
They do not target food allergies and will not be effective against severe reactions to foods. However, some patients complain of itchy mouth or runny nose with certain foods. This syndrome is often not actually a food allergy but a symptom of cross-reactivity with common allergens and it will likely improve significantly with SLIT.
Can I stop taking allergy medications when I start drops?
You should stay on allergy medications at the start of SLIT therapy. At the first follow-up visit (about 12 weeks after treatment begins) your provider will begin to taper the medications. You may find you have already started feeling so much better by the first visit that you are no longer medication-dependent.
If I am on shots, can I transition to drops?
Yes! Talk to your Doctors Express treatment provider; you’ll find the transition is quick and seamless and could start immediately!
Is sublingual immunotherapy treatment FDA approved?
The antigens in the treatment are FDA approved for use in shots. Sublingual therapy is an “off label” use. It is similar to using Albuterol in children, or giving baby aspirin to prevent heart disease. Sublingual application is clinically proven to be safer than injections and is endorsed by the World Health Organization.
