Quick answer
The Wall Pellitory allergy test uses a blood sample to measure immunoglobulin E antibodies directed at wall pellitory pollen, also known as Parietaria. This weed releases pollen that can trigger sneezing, itchy eyes, and nasal congestion in sensitive people. The test is often ordered as part of a seasonal allergy workup and is interpreted by a qualified healthcare provider alongside symptoms.
What this test measures
Wall pellitory is a weed that grows in cracks, walls, and disturbed ground, and it releases lightweight pollen that can travel long distances. In some regions it is a major cause of seasonal allergy symptoms, particularly where the climate is mild. Its pollen season can be long, so symptoms may persist beyond the typical spring or fall window.
The test measures allergen-specific IgE in serum with a laboratory immunoassay. A single blood draw is enough, and the report usually includes a quantitative level and a reactivity class for wall pellitory. Because weed pollens can share some allergens, results are often reviewed with other weed, grass, and tree pollen tests.
A positive result shows sensitization, meaning the immune system has made antibodies against the pollen. It does not prove that the pollen is causing current symptoms, since exposure and individual sensitivity also matter. Clinicians combine the result with a symptom history and other findings before discussing management options.
- Wall pellitory (Parietaria judaica)-specific IgE antibodies
- Total serum IgE
- Quantitative allergen-specific IgE level
- IgE reactivity class for wall pellitory
- Parietaria major allergens (Par j 1, Par j 2)
- Cross-reactive weed pollen allergens
Why people order this test
- Investigate seasonal nasal, eye, or breathing symptoms
- Identify weed pollen sensitization as part of an allergy workup
- Review symptoms that occur during a prolonged pollen season
- Distinguish wall pellitory sensitivity from other weed pollens
- Follow up on symptoms that worsen outdoors
How to prepare
No fasting is required for this blood test. A sample is collected from a vein, usually at the arm, and you can follow your normal routine unless the laboratory provides other instructions.
Understanding your results
Results are usually reported within one to three business days. The report shows the specific IgE level and reactivity class for wall pellitory. Elevated values suggest sensitization, and a qualified healthcare provider explains what the finding means for you.

Frequently Asked Questions
What is wall pellitory?
It is a weed, also called Parietaria, that produces light pollen capable of triggering seasonal allergies. It commonly grows on walls and in disturbed ground.
How is the test done?
A small blood sample is drawn from a vein and analyzed for IgE antibodies that react to wall pellitory pollen.
Do I need to fast?
No fasting is required for this test. Follow any instructions provided with your order.
What does a positive result mean?
It means the immune system has produced antibodies against the pollen. That indicates sensitization, though symptoms also depend on exposure.
When will I get results?
Results are generally available within one to three business days after the sample reaches the laboratory.
