Celery Allergy Test
A celery allergy test uses a blood sample to measure IgE antibodies against celery. It helps explain reactions such as itching, hives, swelling, or digestive symptoms after eating celery or foods that contain it.

Quick answer
The celery allergy test uses a blood sample to measure immunoglobulin E antibodies directed at celery proteins. It is ordered when someone has reactions after eating celery or dishes that contain it, or as part of a broader food allergy panel. The result shows whether sensitization is present, and a qualified healthcare provider interprets it alongside the person's history.
What this test measures
Celery is a common food allergen, and reactions can range from mild oral itching to hives, swelling, or more serious symptoms. Celery belongs to the same plant family as carrot, parsley, and celeriac, so some people react to several of these foods. A blood test can show whether the immune system has produced IgE antibodies that recognize celery proteins.
The test measures allergen-specific IgE in serum with a laboratory immunoassay. A single blood draw is enough, and the laboratory reports the level of celery-specific IgE along with a reactivity class. Celery allergens include Api g 1, a protein that cross-reacts with birch pollen, and Api g 4, a profilin, which can explain reactions to several plant foods at once.
A positive result shows sensitization rather than a confirmed allergy, because symptoms depend on exposure and individual sensitivity. Clinicians interpret the result with a symptom history, and sometimes other food or pollen tests, before deciding whether avoidance or further evaluation is appropriate. Anyone with a history of severe reactions should seek guidance from a qualified healthcare provider.
- Celery-specific IgE antibodies
- Total serum IgE
- Quantitative allergen-specific IgE level
- IgE reactivity class for celery
- Celery allergen component Api g 1 (PR-10 protein)
- Celery allergen component Api g 4 (profilin)
- Celery lipid transfer protein Api g 6
- Cross-reactive birch pollen allergen Bet v 1
Why people order this test
- Investigate reactions after eating celery, celeriac, or mixed dishes
- Support evaluation of oral itching or swelling after raw vegetables
- Clarify a suspected food allergy within a broader panel
- Assess cross-reactivity with birch pollen or other plant foods
- Provide objective information before discussing avoidance with a provider
- Follow up on hives or digestive symptoms of unclear cause
How to prepare
No fasting is needed for this blood test. A sample is collected from a vein, usually at the arm. Follow any instructions provided by the laboratory, particularly if the test is combined with other panels.
Understanding your results
Results are generally available within one to three business days. The report shows the celery-specific IgE level and a reactivity class. An elevated value indicates sensitization, and only a qualified healthcare provider can interpret it in the context of symptoms and exposure.

Frequently Asked Questions
What is a celery allergy test?
It is a blood test that measures IgE antibodies against celery proteins. A positive result shows the immune system recognizes celery, though it does not by itself confirm that symptoms are caused by it.
Do I need to fast before the test?
No fasting is required. The test uses a small blood sample drawn from a vein.
Can celery allergy be linked to other foods?
Yes. Celery shares proteins with birch pollen and with other plants in the same family, such as carrot and parsley. A healthcare provider can review related tests to understand the pattern.
What symptoms can a celery allergy cause?
Reactions may include itching or tingling in the mouth, hives, swelling, abdominal discomfort, or, in some cases, more serious breathing symptoms. Symptoms that are severe or worsening need prompt medical attention.
Does a positive result mean I must avoid celery?
A positive result shows sensitization. Whether avoidance is needed depends on the person's history and symptoms, which a qualified healthcare provider evaluates.
