Blood testing
As a result of food sensitivity testing, the complexes antibody/antigen will get larger. This means that your larger complexes can activate the complement cascade, which in turn initiates inflammatory responses in the body, and consequent detection through blood testing.
The inflammatory response to a food is the main cause of intolerance symptoms. These complexes can also then be deposed in tissue or organs, leading to damage, which can cause uncomfortable and nuisance symptoms to an individual.

Showing themselves to be more adhesive, IgG1 antibodies can be bonded to any antigens. This increases the possibility of cross-reactivity and therefore, there is a lesser number of false-positive results within our blood testing. This means that testing both IgG1 and IgG4 leads to many unnecessary food eliminations.
As an antibody, the IgG4 antibody is a more clinically applicable marker of chronic food-immune reactions and of possible intestinal hyper-permeability. Between IgG1 and IgG4 measurements are less likely to produce false-positives on in-vitro tests. Similarly, when measuring all ranges of IgG, or total IgG, and it is more likely that these all produces a high rate of false-positive reactions.
