The newest development in food intolerance testing is the Food Sensitivities 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.
