Allergen, Tree, Alder Tree
Also known as: ALDER
Use
This test measures allergen-specific IgE levels for Alder Tree. It is used to assess the probability of an IgE mediated clinical reaction to this specific allergen. The test provides quantitative results that may help in the diagnosis and management of allergy to Alder Tree by correlative use with clinical history and in vivo reactivity tests. Although increasing concentrations of allergen-specific IgE may indicate a higher probability of an allergic response, they do not necessarily correlate with the severity of clinical symptoms.
Special Instructions
Multiple patient encounters should be avoided during collection. Serum should be separated from cells as soon as possible and transferred to an ARUP Standard Transport Tube. Refer to the "Allergen Specimen Collection Instructions" for more detailed guidance when multiple allergens are ordered.
Limitations
Concentrations of allergen-specific IgE provided by this test do not predict severity of allergic reactions nor correlate with skin test responses. A negative result does not exclude the possibility of allergy or anaphylaxis, and results should always be interpreted in conjunction with clinical history and other diagnostic indicators.
