Class 0 indicates that the allergen level was undetectable, while Class 6 indicates that the allergen level had a strong positive. Allergen results are determined based on the igr of IgE antibodies in the blood specific to without particular allergen. For dog allergies, the IgE antibodies would correspond to proteins found in dog dander ige saliva. A Class 0 allergy indicates that the IgE levels were undetectable in the blood.
