Test Code ALADD or LAB2129 Additional Childhood Allergens (Added to Respiratory Allergy Panel), Serum

Important Note

Please Note: This test is only available to be ordered in conjunction with requests for the Respiratory Allergen Profile.

If the Respiratory Allergen Panel is requested in conjunction with the Childhood Allergy Panel, please order RSAL (LAB2259) for the Respiratory Allergen Panel and ALADD for Additional Allergens included within the Childhood Allergy Panel.

For additional information, please see the test code listing under "Resources" on the left hand side of this page.

Optimal Collection Volume: 

5 mL; full tube
Minimum Volume:

3 mL
Collection Instructions:

Gently invert the sample 5-6 times after collection.

Methodology

Phadia ImmunoCAP - Fluorescence enzyme immunoassay

Reference Ranges

Specific IgE - All Ages
Value (kU/L) Interpretation Class
< 0.10 Negative Negative
0.10 - 0.35 Equivocal/Very Low Class 0/1
0.36 - 0.70 Low level of allergy, indicative of ongoing sensitization Class 1
0.71 - 3.50 Moderate level of allergy, indicative of stronger ongoing sensitization Class 2
0.35 - 17.50 High level of allergy, indicative of high-level sensitization Class 3
17.51 - 50.00 Very high level lof allergy, indicative of ver high-level sensitization Class 4
50.01 - 100.00 Very high level of allergy, indicative of very high-level sensitization Class 5
> 100.00 Very high level of allergy, indicative of very high-level sensitization Class 6

 

Interpretive

Positive results indicate the possibility of allergic disease induced by one or more allergens present in the multi-allergen cap.

 

Negative results may rule out allergy, except in rare cases of allergic disease induced by exposure to a single allergen.

 

Detection of IgE antibodies in serum (Class 1 or greater) indicates an increased likelihood of allergic disease as opposed to other etiologies and defines the allergens that may be responsible for eliciting signs and symptoms.

 

The level of IgE antibodies in serum varies directly with the concentration of IgE antibodies expressed as a class score or kU/L.
