Ulta Lab Tests

Regional Allergy Tests

Allergy seasons differ by region. A coastal spring birch bloom, a Midwestern ragweed fall, or a humid Southern summer can each drive symptoms. “Regional Allergy Tests” let you build a location-matched sIgE blood panel that covers the trees, grasses, weeds, and key indoor allergens most likely to affect you. Blood allergen-specific IgE (sIgE) requires only a standard blood draw and—unlike skin testing—is not blocked by antihistamines.


Use the regional menus below to select single allergens (with test numbers) and add indoor staples (dust mites, molds, cockroach). Results confirm sensitization and help you and your clinician align findings with local seasons, microclimates, and indoor exposures.

Signs, Symptoms & Related Situations

  • Nose/eyes: sneezing, runny/stuffy nose, itchy/watery eyes, post-nasal drip

  • Chest: cough, wheeze, chest tightness (often worse outdoors on high-pollen days)

  • Timing clues: spring (trees), late spring–summer (grasses), late summer–fall (weeds); year-round in damp or carpeted homes (mites/molds)

  • Environments: yard work, open windows, bedrooms with carpeting/bedding, basements/bathrooms with moisture

  • Urgent care: trouble breathing, severe wheeze, or facial swelling—seek immediate help
    All symptoms should be evaluated by a qualified clinician.

Why These Tests Matter

What testing can do

  • Confirm sensitization to region-relevant pollens and indoor allergens

  • Guide timing for medications, filter changes, and exposure reduction

  • Support planning for further evaluation (e.g., component testing or skin tests in complex patterns)

What testing cannot do

  • Predict exact severity (sIgE reflects likelihood, not intensity)

  • Replace clinician-directed skin testing or challenge when needed

  • Diagnose non-IgE triggers (irritants, infections)

How the Testing Process Works

  1. Map your seasons & spaces: note when/where symptoms are worst.

  2. Select tests: choose regional trees, grasses, weeds by code and add indoor allergens.

  3. Collect: routine blood draw (antihistamines do not affect sIgE).

  4. Results: access securely within a few days; values are quantitative.

  5. Next steps: review with your clinician to align results with seasonal plans, indoor moisture control, filtration, and medication timing.

Interpreting Results (General Guidance)

  • Positive sIgE that matches your season/exposure supports clinical allergy.

  • Multiple positives are common; prioritize by history (which months/rooms).

  • Low/borderline results may still matter on high-pollen days—consider component testing or skin tests if patterns are unclear.

  • Negative sIgE with convincing symptoms: consider non-IgE triggers, different allergens, or further evaluation.

Choosing Panels vs. Individual Tests

  • Targeted approach: select single allergens by code to mirror local exposures.

  • Broader screen: combine several trees grasses weeds from your region and add the indoor core.

  • Complex patterns: consider component testing (e.g., Bet v 1, Phl p 1/5, Amb a 1; profilin/polcalcin—codes vary) or clinician-directed skin testing.

FAQs

Do I need to stop antihistamines before the blood test?
No. Antihistamines do not affect sIgE blood testing (they can affect skin tests).

Why am I positive to many pollens at low levels?
Pan-allergens (profilins/polcalcins) can cause broad low-level positives; component testing clarifies this.

Can indoor allergens make seasonal symptoms worse?
Yes—dust mites, molds, cockroach often drive year-round congestion that amplifies seasonal flares.

Will sIgE levels drop if I change my environment?
Symptoms often improve quickly; sIgE may decline slowly over months to years and can persist despite control.

Regional Allergies and Lab Testing - What You Need to Know

One of the most common health issues in the United States is allergies. Each year, more than 50 million people in America suffer from some type of allergy, which can be serious enough for hospitalization in some cases. 

If you are experiencing allergy symptoms in certain parts of the country, you may have regional allergies. However, there are ways that you can take control of your allergies with regional allergy tests. Keep reading this article for everything you need to know about regional allergy testing and how it can help you. 

What Are Regional Allergies?

Regional allergies are allergies that vary considerably due to location.

For example, allergens will differ in every place you go, including different types of weeds, dust, and even grass. When you are used to the allergens that you are exposed to, you can become more sensitized to other sets of allergens in different locations. 

Risk Factors for Regional Allergies

The risks for regional allergies are similar to the risks of typical allergies. The symptoms can vary in severity depending on how bad your allergies are. Typically, regional allergies are just a minor inconvenience with sneezing, itchiness, and other less extreme symptoms. 

Some risks come if you develop more severe regional allergies. These can lead to ear and lung infections, migraines, skin conditions, and more. If you have difficulty breathing, it may be best to consult with a doctor to identify your next steps. 

Causes of Regional Allergies

One of the biggest causes of regional allergies is when you are exposed to allergens that are not present in the geographical area where you live. If you move to another geographical area with different vegetation, you can easily become allergic to these plants and other allergens. 

What Are the Signs and Symptoms of Regional Allergies?

The signs and symptoms of regional allergies are similar to the signs and symptoms of other types of allergic reactions. You will often find that you have itchy and watery eyes, an itchy or running nose, and even sneezing. 

Other types of allergic reactions may include rashes, hives, and even difficulty breathing. 

How Are Regional Allergies Diagnosed?

Regional allergies are diagnosed with region-specific allergy lab tests. If you have had trouble with allergies in specific parts of the country, you can find lab tests for allergens specific to that part of the country. 

Regional allergy lab tests are performed using a blood draw. The blood specimen is sent to a national testing facility where it is tested to see how it reacts to the allergens of the region you are testing for. 

The Lab Tests to Screen, Diagnose, and Monitor Regional Allergies

Ulta Lab Tests offers regional allergy tests that you can order without a doctor’s referral or insurance. Each of our regional allergy tests will test a different region of the country and include allergens specific to that region, listed as biomarkers. 

Here are some of our most common allergy tests that will help as you monitor your regional allergies. 

FAQs About Regional Allergies and Lab Testing for Regional Allergies

Will Moving Make My Allergies Go Away? 

In some cases, having regional allergies is due to a specific allergen in the area where you live. However, many allergens are difficult to avoid and can be found in many different parts of the country. While moving may help your allergies improve, you would have to learn more about common allergens in the area.

What are The Most Common Regional Allergies?

The most common regional allergies come from vegetation and plants that are not common in other parts of the country. You can typically find these with tree pollen, different types of grasses, different types of trees, and more. Other allergens include dust mites, animal dander, and more. 

What Types of Lab Tests are Available For Regional Allergies? 

There are many lab tests available for regional allergies, with the most common being blood tests. Skin or patch tests may be performed by a physician’s office.
