Onion
Use
The Onion IgE test is used to evaluate allergic sensitivity to onions. It measures the specific IgE antibodies to onions in the patient's serum, which can help in diagnosing allergic reactions to onion consumption or exposure. The results provide information about the severity of the allergic response, which can help guide dietary and environmental management for individuals with onion allergies.
Special Instructions
Testing schedules may vary and additional time might be required for confirmatory or additional reflex tests. Turnaround time is defined based on the usual number of days from specimen pickup to result release.
Limitations
As with all immunoassays, the Onion IgE test may not detect all allergic reactions, particularly if they are not IgE-mediated. False positives and false negatives can occur, and results should be interpreted in the context of the patient's clinical history and other diagnostic tests. Cross-reactivity with other allergens is possible, which may affect the specificity of the test.
