At home food sensitivity test

These are kits designed for personal use to identify potential food sensitivities by measuring the body's immune response to various foods. The test works by detecting the levels of specific antibodies, such as IgG and IgG4, in the blood after exposure to food antigens. Available from multiple providers, the cost of these tests can range from $132 to $229. However, the effectiveness of these tests is still under debate due to limited supporting evidence.
