    Test Description

    Cytotoxic Food Sensitivity, Basic

    The sensitized cells react with a specific allergen (purified antigen and additives). The reaction is a combination delayed (Type IV) and immediate (Type I) reaction. Allergic reactions are read under a light microscope at 400x power. The results are graded as negative (same as negative control), plus 1, plus 2, plus 3 and plus 4.

    The Basic Cytotixic Food Sensitivity Profile includes 24 specific (common) food allergens (these are also included in the Standard Cytotoxic List #1 which is listed as a separate "product"): apple, banana, seedless grape, orange, soybean, corn, onion, white potato, tomato, chicken, whole egg, cow's milk, coffee, tea, cane sugar, white flour, oat, rice, whole wheat, MSG, Nutrasweet, chocolate, vanilla, yeast.
