Aspen (Populus tremuloides) IgE
Use
The Aspen (Populus tremuloides) IgE test is designed to detect specific IgE antibodies to Aspen pollen in the serum. This test is used as part of allergy diagnostics to identify sensitization in patients with respiratory allergic symptoms, such as rhinitis or asthma. The detection of specific IgE antibodies can help guide allergen avoidance strategies and inform the use of immunotherapy.
Special Instructions
Not provided.
Limitations
The Aspen IgE test does not measure allergen-specific IgE levels for other pollen types or potential allergens. Results might not correlate with clinical symptoms in all patients due to variability in individual immune responses. Grossly hemolyzed, lipemic, or icteric samples may yield inaccurate results and are therefore inappropriate for testing. Repeat testing or alternative methods may be recommended if results are inconsistent with clinical evaluations.
