Using ELISA technology, US BioTek assesses a patient's serum for the presence of immediate and delayed reactions to food antigens, namely immunoglobulin E (IgE) and immunoglobulin G (IgG) respectively. Our inhalant allergy panels assess for IgE. Allergic reactions to foods and inhalants are characterized by enhanced allergen-specific immunoglobulin serum levels with activation of immune mediators of inflammation. Research indicates that food and inhalant allergies are implicated in a number of health problems. Through US BioTek ELISA testing, we provide a useful tool with which an individual’s sensitization to food and inhalant allergens can be assessed.
