Allergens, Pediatric Inhalants, Southwest
Also known as: SWPED
Use
This test is used to detect pediatric inhalant allergens specific to the Southwest region, which includes allergens such as Bermuda grass pollen, cat and dog dander, common ragweed, and others. It helps in diagnosing allergic reactions linked to these environmental factors by measuring allergen-specific IgE levels in serum. Understanding IgE concentrations aids clinicians in assessing allergic risk and potential reactions in children exposed to these specific allergens.
Special Instructions
Avoid multiple patient encounters when collecting samples. Separate the serum from cells as quickly as possible to maintain specimen integrity. Use the ARUP Standard Transport Tube to ensure the specimen meets testing requirements.
Limitations
Results showing allergen-specific IgE levels between 0.10-0.34 kU/L require specialist interpretation as their clinical relevance is undetermined. Increasing concentrations of IgE may not directly correlate with actual clinical reactions or skin test results. A negative result does not exclude the possibility of clinical allergy or anaphylaxis.
