Quick answer
The Region 16 Allergies panel is a regional IgE blood test covering 22 allergens common in inland areas of the Pacific Northwest. It evaluates sensitization to the tree, grass, and weed pollens, molds, and indoor allergens typical of valleys and highlands east of the coastal range. The panel is used when symptoms suggest allergy but the specific triggers need to be sorted out.
What this test measures
Inland northwestern environments blend dry valleys, forested slopes, and high plains. Tree pollen from alder, birch, and related species is prominent in spring, grasses pollinate through late spring and summer, and weeds such as ragweed and sage contribute later in the season. Mold spores can be common in damp conditions, and indoor allergens remain relevant through the colder months when people spend more time inside.
This panel measures allergen-specific IgE for 22 regionally selected allergens from one blood sample. Targets may include spring tree pollens, grass pollens, weed and shrub pollens, mold spores, and common indoor allergens. Each allergen is reported with a quantitative level and a graded class so patterns can be compared.
People who live in inland northwestern communities and notice seasonal or persistent nasal, eye, or airway symptoms may find this panel useful. It can also help when symptoms differ from those of the wetter coastal side of the region. A qualified healthcare provider interprets the findings with the person's location, exposures, and symptom calendar.
- Tree pollen IgE (alder, birch, and related species as included)
- Grass pollen IgE (timothy, bluegrass, and related grasses as included)
- Weed and shrub pollen IgE (ragweed, sage, and related plants as included)
- Mold spore IgE (Alternaria, Cladosporium, and related molds as included)
- Dust mite IgE when included
- Cat and dog dander IgE when included
- Allergen-specific IgE class for each of the 22 panel allergens
Why people order this test
- Investigate spring tree pollen symptoms in inland valleys
- Screen summer grass and late-season weed pollens together
- Assess whether mold spores contribute to damp-season symptoms
- Check indoor allergen sensitization during colder months
- Clarify which regional allergens to discuss with a clinician
How to prepare
No fasting is required, and the panel can be performed at any time of year. Follow the lab's standard instructions for blood collection.
Understanding your results
Results typically return within one to three business days. Each allergen is reported separately, allowing tree, grass, and weed patterns to be distinguished. Positive results indicate sensitization rather than a diagnosis, and a qualified healthcare provider interprets them with the person's symptoms.

Frequently Asked Questions
How does inland pollen differ from coastal pollen?
Inland areas tend to be drier and have different tree, grass, and weed mixes than coastal zones, so regional panels are tailored to each environment.
When is tree pollen highest in this region?
Many inland trees pollinate in spring, though the exact timing shifts with elevation and local weather.
Is mold a concern in a dry inland climate?
Mold can grow in damp indoor spaces and in irrigated or shaded outdoor areas, so panels often include common mold allergens.
Can symptoms be year-round here?
Year-round symptoms may reflect indoor allergens, overlapping pollen seasons, or other causes that a clinician can evaluate.
Is one blood sample enough?
Yes. The full panel is measured from a single blood draw.
