How do I reconcile the recommendations by physicians and medical society (against immunoglobulin G testing) with the availability of these tests?
We have found that many of the customers who order this test have already planned to undertake a food elimination diet because they have been unable to identify the source of their symptoms, either alone or in conjunction with their healthcare provider.
The IgG results are used to determine which foods they should start to eliminate and then add back one at a time to determine which is the source of their unwanted symptom generation. If they are able to identify a food or foods that are making them feel unwell, then no reconciliation is necessary. If they are unable to identify any foods that cause their symptoms, then they are able to take that information back to their health care providers and to use that information to help determine what else could be their source of symptom production.
