This at-home test measures your body's IgG response to 96 foods to help provide guidance on what foods may be the best to eliminate. EverlyWell tests are reviewed and approved by an independent board-certified physician within your state. This ensures that any test ordered is relevant to your health and wellness. Each partner lab we choose to work with is CLIA-certified (Clinical Laboratory Improvement Amendments). This means they have to meet high standards to obtain both state and federal certifications and submit themselves to regular inspections.
