Allergen, Tree, Acacia Tree

Also known as: ACACIA

Clinical Use

Order Test

Use

The Allergen, Tree, Acacia Tree test is crucial for identifying the presence of allergen-specific IgE antibodies to Acacia Tree (Acacia longifolia) allergens. This could help in diagnosing allergic reactions associated with Acacia trees in patients who exhibit allergy symptoms such as rhinitis, asthma, or other IgE-mediated conditions. The test quantitatively measures IgE levels using the ImmunoCAP Fluorescent Enzyme Immunoassay method, providing an assessment of exposure and sensitization to this specific allergen.

Special Instructions

Multiple patient encounters should be avoided in sample collection to prevent contamination. It is important to follow the Specimen Collection and Handling Instructions to ensure adequate volume for allergen testing. In cases of multiple allergen orders, refer to the appropriate collection instructions to optimize the testing process.

Limitations

Allergen-specific IgE concentrations may not directly correlate with the severity of clinical symptoms or skin test results. A negative result does not exclude the possibility of an allergy or anaphylactic reaction upon exposure. Clinical correlation with patient history and other diagnostic tests is essential. Results in the range of 0.10-0.34 kU/L require specialist interpretation as their clinical significance is undetermined. Concurrent clinical assessment is recommended for comprehensive evaluation.
