The merits of using the FIT Tests to detect Food Sensitivities
The FIT Tests: Comparison with conventional IgG only tests:
Food sensitivity tests that measure IgG alone are less sensitive than the FIT Tests which measure both IgG and Immune Complexes. The net result is that tests measuring only IgG will under report the occurrence of foods that cause food sensitivities. The FIT Tests which measure both IgG and Immune Complexes is more sensitive and generates results that give a 95% confidence that foods are either positive or negative in an easy to interpret and understand report whereas, IgG only tests that give broad ranges of reactivity which are hard to interpret and even harder for the patient to understand.
The FIT Tests employ a conjugate which contains bothanti-Human IgG and anti-Human-C3d linked to an enzyme. The anti-Human-IgG is specific for IgG heavy chains subclasses 1-4 whereas, the anti-C3d reacts with an epitope on C3d which is covalently bound to IgG in the immune complex (IC-C3d). The dual conjugate binds to both IgG and C3d and increases sensitivity when compared to conventional tests that use only anti-Human IgG. The increased sensitivity of the FIT Tests over conventional IgG only tests are illustrated by the data in the patent (#8,309,318)
The FIT Test: Practical implications
The information gained from the FIT Tests can be directly applied to diet management with the overall goal of lessening the symptoms associated with certain conditions. If the foods that screen positive for immune complexes and IgG are eliminated from the diet, inflammation should be reduced and the patient should experience some relief from the symptoms associated with certain conditions. Our tests are not a “cure all” solution but rather a tool which identifies potentially harmful foods which then can be eliminated from the diet in an attempt to lessen symptoms associated with conditions that are refractory to conventional techniques. Unlike medicines that have side effects, diet management is a natural process that controls the intake of reactive foods, while at the same time, providing complete nutrition to prevent any undesired side effects.
