Dog Fennel IgE Test
The Dog Fennel Allergy Test measures IgE antibodies to mayweed pollen, a common weed allergen. It helps identify whether seasonal sneezing, itchy eyes, or nasal congestion are linked to this pollen.

Quick answer
The Dog Fennel Allergy Test uses a blood sample to measure immunoglobulin E antibodies against dog fennel, also called mayweed, and its pollen. Dog fennel is a weed whose airborne pollen can trigger hay fever symptoms in sensitive people. The test connects seasonal sneezing, itchy eyes, and congestion to a specific pollen source and is read with a symptom history.
What this test measures
Dog fennel, known scientifically as mayweed, is a flowering weed found along roadsides, fields, and disturbed ground. Like other weeds, it releases lightweight pollen that can travel on the wind. People with pollen allergy may notice sneezing, runny nose, itchy or watery eyes, and nasal congestion when levels rise.
This test measures allergen-specific IgE in serum using a quantitative immunoassay. A single blood draw is enough, and the laboratory reports the antibody level along with a reactivity class. Because many weed pollens share similar allergens, the result is often reviewed with other weed and grass tests.
A positive result shows sensitization rather than confirming that symptoms are caused by this pollen. Clinicians interpret the finding with the timing and location of symptoms and other test results. The information can help guide a conversation about avoidance and further evaluation.

Why people order this test
- Investigate seasonal sneezing, itchy eyes, or congestion
- Identify sensitivity to a specific weed pollen
- Compare reactivity across weed and grass pollens
- Support an allergy workup with objective data
- Follow up when symptoms peak during weed season
- Provide context before discussing avoidance with a provider
How to prepare
No fasting is required for this blood test. A sample is collected from a vein, usually at the arm. Follow any instructions provided by the laboratory regarding current medications.
Understanding your results
Results are generally available within one to three business days. The report shows the specific IgE level and reactivity class for dog fennel pollen. An elevated value suggests sensitization, and a healthcare provider explains what it means in context.

Frequently Asked Questions
What is dog fennel?
Dog fennel, also called mayweed, is a common weed whose airborne pollen can trigger allergic symptoms in sensitive people.
How is the test done?
A small blood sample is drawn from a vein and analyzed for IgE antibodies that react to mayweed pollen.
Do I need to fast?
No fasting is required for this test unless it is bundled with other tests that call for it.
What does a positive result mean?
It shows that the immune system has produced IgE antibodies against the pollen, which indicates sensitization rather than confirming that symptoms are caused by it.
