The newest development in food intolerance testing is the FoodSafe IgG4 Test, which requires only a small amount of blood for testing of 95 food antigen–now with free additional candida screen included (Candida Albicans). This allows the patient to do the test at home or for the doctor to do in-office without a venipuncture. The finger is pricked with a lancet and then drops of blood are placed on a blood spot collection card. The card is air-dried and returned to the laboratory for assessment. IgG results are ranked according to their concentrations, and then reported as low, moderate, or avoid.
The information provided in this report enables the client to design an appropriate diet to exclude the reactive foods. With this test you can determine the primary cause of adverse food reactions. A food that causes an IgG response is referred to as delayed hypersensitivity, which may come and go in cycles, depending on whether the food is eaten or avoided.
