Allergen Profile, Cat, Dog and Horse, IgE With Component Reflex
Use
Allergen component testing offers advantages over the use of a complete extract, especially in poly-sensitized individuals, given its usefulness for distinguishing between sensitizations specific to singular species and sensitizations due to cross-reactivity.
Special Instructions
Not provided.
Limitations
This test cannot identify all possible allergenic proteins and does not replace detailed clinical evaluation. The possibility of cross-reactivity among different mammalian species could lead to positivity in the absence of direct sensitization. The presence of specific IgE needs to be interpreted in conjunction with a patient’s clinical history due to potential for cross-reactivity causing misidentification.
