Quick answer

The Region 15 Allergies panel is a regional IgE blood test covering 23 allergens common in high desert and southern mountain areas of the western United States. It evaluates sensitization to shrub, tree, grass, and weed pollens as well as molds and indoor allergens typical of these environments. The panel is used when symptoms suggest allergy but the specific triggers need clarification.

What this test measures

High desert and mountain-fringe environments have a pollen profile shaped by aridity, elevation, and wind. Sagebrush and rabbitbrush release late-season pollen, juniper and other trees pollinate at different points in the year, and warm-season grasses add summer pollen. In southern parts of the region, Bermuda grass and weeds extend the allergy season well into autumn.

This panel measures allergen-specific IgE for 23 regionally selected allergens from one blood sample. Options typically include desert shrub pollens, tree pollens, grass pollens, weed pollens, mold spores, and common indoor allergens. Results are reported per allergen with a quantitative value and a graded class.

People who live in high desert communities or spend time in mountain areas and notice recurring nasal, eye, or airway symptoms may order this panel. It can also help when symptoms appear during dry, windy periods that do not match typical pollen seasons elsewhere. A qualified healthcare provider interprets the results with the person's environment and symptom pattern.

  • Desert shrub pollen IgE (sagebrush, rabbitbrush, and related shrubs as included)
  • Tree pollen IgE (juniper and related species as included)
  • Grass pollen IgE (Bermuda and related grasses as included)
  • Weed pollen IgE (ragweed 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 23 panel allergens

Why people order this test

  • Investigate allergy symptoms during dry, windy periods
  • Check shrub and weed pollen sensitization common in high desert areas
  • Screen tree and grass pollens adapted to arid climates
  • Assess whether mold or indoor allergens play a role in persistent symptoms
  • Identify which regional allergens to review with a clinician

Frequently Asked Questions

What grows in high desert areas that causes allergies?

Shrubs such as sagebrush and rabbitbrush, juniper trees, warm-season grasses, and weeds including ragweed are common regional pollen sources.

Can wind make allergy symptoms worse in dry climates?

Wind can lift pollen and dust into the air, increasing exposure. Testing shows whether sensitization to those allergens is present.

Is mold included in a desert panel?

Yes. Mold spores can be present in soil, on plants, and in buildings, so many regional panels include common mold allergens.

Do I need a referral to order this panel?

Requirements vary by testing service and clinician. The ordering process is explained when the test is selected.

Can the panel explain symptoms that occur in winter?

Winter symptoms may relate to indoor allergens or to trees that pollinate in cooler months. Individual results help guide that discussion with a clinician.
