Quick answer
The Region 12 Allergies panel is a regional IgE blood test covering 24 allergens common in the desert areas of the southwestern United States. It evaluates sensitization to the tree, weed, and grass pollens, molds, and indoor allergens typical of hot, arid environments. The panel is used when symptoms suggest allergy but individual triggers have not been identified.
What this test measures
Desert environments have a distinctive pollen calendar. Mesquite, palo verde, and other desert trees release pollen in spring, while sagebrush and related shrubs add late-summer and autumn pollen. Warm-season grasses such as Bermuda pollinate through the hot months, and mold spores can still be present despite low humidity. Indoor allergens like dust mite remain a year-round consideration in air-conditioned homes.
This panel measures allergen-specific IgE for 24 regionally relevant allergens in one blood sample. Depending on its configuration, targets may include desert tree pollens, shrub and weed pollens, warm-season grass pollens, mold spores, and indoor allergens. Results are reported for each allergen with a quantitative value and graded class.
People who live in desert communities and experience seasonal congestion, itchy eyes, or airway symptoms may find this panel useful. It can also add clarity when a person has moved from a different climate and symptoms change. A qualified healthcare provider interprets the result with the person's environment and symptom pattern.
- Desert tree pollen IgE (mesquite, palo verde, and related species as included)
- Shrub pollen IgE (sagebrush and related shrubs as included)
- Warm-season grass pollen IgE (Bermuda 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 24 panel allergens
Why people order this test
- Investigate spring tree pollen symptoms in desert communities
- Check shrub and weed pollen sensitization that peaks later in the year
- Assess whether indoor allergens contribute to year-round symptoms
- Evaluate allergy symptoms that changed after moving to a desert climate
- Identify which regional allergens merit further discussion with a clinician
How to prepare
No fasting is needed, and the panel can be performed at any time of year. Follow the lab's routine instructions for the blood draw.
Understanding your results
Results typically return within one to three business days. The report presents each allergen separately so that spring and late-season patterns can be compared. Positive results show sensitization, and a qualified healthcare provider interprets them together with the person's symptoms.

Frequently Asked Questions
Why include desert trees in this panel?
Trees such as mesquite and palo verde are common in arid southwestern areas and release pollen that can trigger seasonal symptoms.
Can mold allergy occur in a dry climate?
Yes. Mold spores can be present outdoors and in indoor spaces even in arid regions, so regional panels often include common mold allergens.
Does air conditioning affect indoor allergens?
Air conditioning changes indoor humidity and airflow, which can influence dust mite and mold exposure. The panel can show whether sensitization to these allergens is present.
Is a blood draw enough for this panel?
Yes. A single blood sample is used to measure IgE against all of the allergens in the panel.
How should I use the results?
Share the report with a qualified healthcare provider, who can interpret it alongside the symptom history and recommend any follow-up.
