Allergen, Food, Celery
Also known as: CELERY
Use
This test assesses the presence of allergen-specific IgE antibodies to celery. IgE antibodies play a key role in allergic reactions, and increased levels may indicate a sensitivity to celery, potentially resulting in symptoms such as oral allergy syndrome, hives, or in severe cases, anaphylaxis. However, the presence of IgE does not always correlate with the severity of clinical allergic responses; thus, results must be interpreted in conjunction with the patient's clinical history and other allergy tests.
Special Instructions
Serum must be separated from cells within 2 hours of collection to ensure sample integrity. For multiple allergen orders, refer to "Allergen Specimen Collection Instructions" on the ARUP website to ensure appropriate specimen handling and transport requirements.
Limitations
While the test measures the concentration of IgE, the levels detected do not necessarily predict the severity of allergic reactions. Correlation with clinical history and other diagnostic testing is essential to accurately interpret results. False positives or negatives may occur, and a negative result does not necessarily rule out a celery allergy or even anaphylaxis.
