Allergen, House Dust Stier
Also known as: HOUSESTIER
Use
The Allergen, House Dust Stier test is used to detect and quantify allergen-specific IgE in the patient's serum. It helps determine potential allergic reactions to house dust mites. This test measures allergen-specific IgE levels and aids specialists in assessing the likelihood of an IgE-mediated clinical reaction. The clinical relevance of low levels in the range of 0.10-0.34 kU/L is undetermined and requires correlation with clinical history and in vivo reactivity.
Special Instructions
Multiple patient encounters should be avoided when collecting the specimen. The serum should be separated from cells as soon as possible or within 2 hours of collection. For multiple allergen orders, refer to the Allergen Specimen Collection Instructions at ARUP's testing resources page.
Limitations
This test detects and quantifies allergen-specific IgE to house dust mites but does not correlate directly with the degree of clinical response or skin testing results when the patient is challenged with a specific allergen. A negative result does not rule out the possibility of a clinical allergy or even anaphylaxis. Cross-reaction with other allergens or proteins is possible, and test results should be interpreted in conjunction with clinical findings and patient history.
