Testing Algorithm

Testing begins with analysis of dog dander IgE. If dog dander IgE is negative (<0.10 kU/L), testing is complete.

 

If dog dander IgE is 0.10 kU/L or more, then 6 dog dander components (Can f 1, Can f 2, Can f 3, Can f 4, Can f 5, Can f 6) are performed at an additional charge.

Concentrations of 0.70 kU/L or more (class 2 and above) will flag as abnormally high.

Reference values apply to all ages.

Interpretation

When detectable total dog dander IgE antibody is present (≥0.10 IgE kUa/L), additional specific component IgE antibody testing will be performed. If at least one potential specific allergenic dog dander component IgE is detectable (≥0.10 IgE kUa/L), an interpretative report will be provided.

 

When the sample is negative for total dog dander IgE antibody (<0.10 IgE kUa/L), additional testing for specific dog component IgE antibodies will not be performed. Negative IgE results for total dog dander antibody may indicate a lack of sensitization to potential dog allergenic components.

Method Description

Specific IgE from the patient's serum reacts with the allergen of interest, covalently coupled to an ImmunoCAP. After washing away nonspecific IgE, enzyme-labeled anti-IgE antibody is added to form a complex. After incubation, unbound anti-IgE is washed away, and the bound complex incubated with a developing agent. After stopping the reaction, the fluorescence of the eluate is measured. Fluorescence is proportional to the amount of specific IgE present in the patient's sample (ie, the higher the fluorescence value, the more IgE antibody is present).(Package insert: ImmunoCAP System Specific IgE FEIA.
