Interpretive Data

Allergen results of 0.10-0.34 kU/L are intended for specialist use as the clinical relevance is undetermined. Even though increasing ranges are reflective of increasing concentrations of allergen-specific IgE, these concentrations may not correlate with the degree of clinical response or skin testing results when challenged with a specific allergen. The correlation of allergy laboratory results with clinical history and in vivo reactivity to specific allergens is essential. A negative test may not rule out clinical allergy or even anaphylaxis. 

Alpha-lactoalbumin (Bos d 4) and Beta-lactoglobulin (Bos d 5) are heat labile and associated with a risk for reaction to fresh milk. Casein (Bos d 8) is heat stable and associated with a risk for reaction to all forms of milk. Note:  Allergens included in this panel:  Alpha-lactoalbumin (Bos d 4), Beta-lactoglobulin (Bos d 5), Casein (Bos d 8) and Milk (Cow's).
