Quick answer
The Region 11 Allergies panel is a regional IgE blood test covering 25 allergens common across the interior western states. It evaluates sensitization to pollens and other allergens typical of desert, mountain, and high-plains environments. The panel is used when seasonal or year-round symptoms suggest allergy but the specific triggers are unclear.
What this test measures
The interior West combines arid valleys, mountain slopes, and high plains, and its allergen profile reflects that mix. Sagebrush and other shrubs release pollen in late summer and autumn, juniper and cedar species pollinate at various points in the year, and warm-season grasses such as Bermuda release pollen through the summer. Weed pollens, including ragweed and pigweed, add to the autumn load in many valleys.
This panel measures allergen-specific IgE for 25 regionally selected allergens from a single blood sample. Options typically span shrub and tree pollens, grass pollens, weed pollens, mold spores, and common indoor allergens. Each allergen is reported with a quantitative antibody level and a graded class so that patterns across the panel can be compared.
People living in or moving to the interior West who notice recurring nasal, eye, or airway symptoms may order this panel. It can also help distinguish seasonal pollinosis from year-round indoor triggers. A qualified healthcare provider interprets the findings with the person's symptom timing, location, and other test results.
- Desert shrub pollen IgE (sagebrush and related shrubs as included)
- Tree and juniper pollen IgE (cedar, juniper, and related species as included)
- Grass pollen IgE (Bermuda, timothy, and related grasses as included)
- Weed pollen IgE (ragweed, pigweed, and related weeds as included)
- Mold spore IgE (Alternaria, Cladosporium, and related molds as included)
- Dust mite and indoor allergen IgE when included
- Allergen-specific IgE class for each of the 25 panel allergens
Why people order this test
- Investigate late-summer and autumn symptoms tied to shrub and weed pollen
- Screen pollens from several altitude and climate zones in one sample
- Assess year-round symptoms that may involve indoor allergens
- Support a move or travel-related allergy evaluation
- Narrow down which regional allergens to review with a clinician
How to prepare
No fasting is required, and the panel can be ordered at any time of year. Follow the lab's standard instructions for blood collection.
Understanding your results
Results are generally available within one to three business days. Each allergen is reported separately, so the panel may reveal a single clear trigger or a broad sensitization pattern. Positive results indicate sensitization rather than a diagnosis, and a clinician interprets them with the person's history.

Frequently Asked Questions
What allergens are typical of the interior West?
Regional panels commonly include shrub pollens such as sagebrush, juniper and cedar tree pollens, warm-season grasses, weeds like ragweed, and mold spores, along with common indoor allergens.
Can altitude affect my allergy symptoms?
Pollen seasons shift with elevation and climate. A panel helps identify which pollens are relevant, and a clinician can relate them to where a person lives or works.
Is this panel a replacement for a skin test?
It is an alternative approach that measures IgE in blood. A clinician decides which testing method is most appropriate for the situation.
Do I need to avoid any foods before the test?
No. This is a blood test and does not require dietary preparation.
What happens if the panel is negative?
A negative panel makes pollen sensitization less likely but does not rule out other causes. A clinician can suggest next steps based on symptoms.
