Allergen, Food, Poppy Seed IgE
Also known as: POPPY
Use
The Allergen, Food, Poppy Seed IgE test measures the level of allergen-specific IgE antibodies in the serum. These antibodies can indicate an allergic response to poppy seeds, which may help in diagnosing and managing allergy symptoms. Higher concentrations of allergen-specific IgE are generally associated with a higher probability of allergic reactions, although the test results should always be interpreted in conjunction with the patient's clinical history and in vivo reactivity tests.
Special Instructions
For accurate test results, avoid multiple patient encounters before specimen collection. Ensure proper serum separation from cells as soon as possible, ideally within 2 hours of collection, and transfer the required volume to an ARUP Standard Transport Tube.
Limitations
Results with allergen levels of 0.10-0.34 kU/L require specialist interpretation as their clinical relevance is undetermined. While increasing allergen-specific IgE levels may suggest higher allergen sensitivity, they do not necessarily correlate with clinical response severity or skin test results. It's crucial to contextualize laboratory results with the patient's clinical history and other reactivity information. A negative result does not completely rule out the possibility of an allergy or even anaphylaxis.
