Is a lab based immune stimulation test in which a patient's wbc's are challenged with various substances including foods, additives, colorings, chemicals, medicinal herbs, functional foods, molds and pharmaceutical compounds. The patient's unique set of responses help to identify substances that may trigger potentially harmful immune system reactions. The test objectively classifies a patient's response to each test substance as reactive, borderline or non-reactive. Based on these classifications, a cus-tomized elimination/rotation diet may be designed to effectively eliminate the specific triggers of chronic immune system activation. By reducing this ongoing burden - and in particular, by reversing the sustained and destructive inflammation it produces - normal body functions and immune system balance can be improved.
