What this laboratory test evaluates
Melaleuca (t21) IgE
This test measures the IgE response to melaleuca, helping to identify allergic reactions. It's a quantitative assay used alongside other clinical data to assist in diagnosing allergic diseases. Allergen-specific serum IgE testing, recognized by leading allergy and immunology academies, may be preferred over skin testing in certain situations, such as widespread skin disease, recent antihistamine use, uncooperative patients, or when skin testing poses a significant allergy risk.
When is this test recommended?Healthcare professionals might suggest this test if there's a suspicion of an allergy to melaleuca, especially under conditions that make skin testing unsuitable or risky.
What type of sample is required for this test?0.3 mL serum.
Phlebotomy is required.
Important Considerations:A definitive allergy diagnosis should not rely solely on this test but should include a comprehensive evaluation by a trained healthcare professional of all clinical and laboratory findings.
