The Region 10 Allergies test is a blood test that checks for allergic sensitization to common allergens found in the U.S. Environmental Protection Agency's Region 10 area (the Pacific Northwest and Alaska). It is ordered when a clinician suspects allergies and wants to identify which specific triggers may be causing symptoms.

What it measures

  • Total IgE — Overall level of allergy-related antibody in the blood.
  • Specific IgE to grasses — Antibodies tied to grass pollen, common in Region 10.
  • Specific IgE to trees — Antibodies tied to tree pollen such as alder or birch.
  • Specific IgE to weeds — Antibodies tied to weed pollen such as ragweed.
  • Specific IgE to molds — Antibodies tied to indoor and outdoor mold spores.
  • Specific IgE to dust mites — Antibodies tied to microscopic dust mite allergens.

Who it is for

A primary care clinician, allergist, or immunologist typically orders this test. It may be used when symptoms like sneezing, runny nose, or itchy eyes happen during certain seasons or in specific places.

Preparation

No fasting is required. Tell your clinician about any medications you take, because some antihistamines can affect allergy test results.

Results and what they mean

Results are reported as numeric levels for each allergen, often with a reference range or class. A clinician interprets these alongside your symptoms and history; a positive result alone does not always mean you have an allergy. This is general information, not medical advice.
