What is the purpose of this test?
Order this Celery Allergy IgE Blood Test, which measures the IgE antibody levels in the blood to detect an allergy to celery. Celery is a versatile plant in the Apiaceae family, commonly used for its stalks. It can be grown annually or biennially and is native to Western and Northern Europe, the Middle East, and parts of Asia and Oceania. Celery allergy sensitization has increased in recent years, with six identified allergens, including Api g 1, which is related to birch pollen. Celery allergy is often associated with birch-mugwort-celery syndrome and can cause oral allergy syndrome. Severe reactions may occur in mugwort-sensitized patients.
What causes an allergic reaction to celery?
Celery allergy is associated with six different allergens, including Api g 1, two Lipid Transfer Proteins, a profilin protein called Api g 4, and a new allergen called Api g 7. Celery also contains furanocoumarins which can act as a contact allergen and cause blistering. In rare cases, ingestion of celery can cause severe sunburn and blistering. Celery may trigger a response in the immune system since the body views certain substances as harmful, producing IgE antibodies to combat these invaders. However, these antibodies cause histamine to be released, resulting in the symptoms associated with an allergic reaction.
When should I order a Celery Allergy IgE Blood Test?
Individuals may order this Celery Allergy Blood Test if they have experienced symptoms related to a celery allergy. Allergy symptoms vary depending on the individual, ranging from mild to severe reactions. Most food-related symptoms occur within two hours of ingestion but frequently begin within minutes. In addition, the response can be delayed by four to six hours or even longer in some rare cases.
An allergic reaction may affect the skin, intestinal lining, and air pathways. Individuals with a celery allergy may experience one or more of the following symptoms:
- Tingling sensation near or around the mouth
- Abdominal discomfort
- Nausea or vomiting
- Itching or hives
- Difficulty breathing, swallowing, or wheezing
In some cases, a severe, possibly life-threatening allergic reaction known as anaphylaxis may occur. An anaphylactic response requires immediate medical attention. Signs or symptoms of anaphylaxis may include:
- Rapid or increased heart rate
- Swollen throat or lump making it difficult to breathe
- Low blood pressure
- Extreme dizziness or loss of consciousness
