The Washington & Oregon 22 Allergies Test Panel is a blood test that checks for allergic sensitivity to 22 common allergens, such as pollens, foods, animal dander, dust mites, and molds. It is ordered when a person has ongoing or unexplained allergy symptoms and a clinician wants to identify likely triggers. Results are reported as a panel of specific allergen markers rather than a single number.

What it measures

  • Specific IgE antibodies — Proteins your immune system makes in response to a particular allergen.
  • Tree and grass pollen markers — Common outdoor allergens that cause seasonal sneezing, itching, or watery eyes.
  • Weed and mold markers — Allergens often linked to late-summer or damp-environment symptoms.
  • Animal dander markers — Proteins from cats, dogs, and similar animals that can trigger indoor symptoms.
  • Dust mite markers — Tiny indoor allergens found in bedding, carpet, and upholstery.
  • Food allergen markers — Selected foods that may be linked to reactions after eating.

Who it is for

A primary care clinician, allergist, or other healthcare professional typically orders this panel. It is used for adults or children with persistent allergy-like symptoms or a suspected trigger.

Preparation

No fasting is usually required. Tell the clinician about any allergy medications you take, because some can affect testing.

Results and what they mean

Results list each allergen with a level or class, which a clinician interprets alongside your symptoms and history. A positive result does not always mean you have an allergy, and a negative result does not rule one out. This is general information, not medical advice; discuss your results with a qualified clinician.
