The FoodSafe™ Total IgG (222) Profile measures immune reactions to 222 foods across all major food groups using a simple at-home fingerstick kit. This panel evaluates all IgG subclasses (IgG1, IgG2, IgG3, and IgG4) to capture a wide spectrum of delayed immune responses that may be linked to chronic inflammation and long-term health concerns.

By assessing both broad and localized reactions, this test can help identify potential food triggers behind symptoms such as fatigue, brain fog, joint discomfort, skin flare-ups, migraines, digestive issues, and sinus congestion. Results are categorized as low, moderate, or high reactivity, making it easier to design a targeted elimination diet with your healthcare provider.

Includes: 

• Testing for 222 foods across dairy, meats, fish, shellfish, vegetables, grains, nuts, spices, fruits, and miscellaneous categories
• Analysis of all IgG subclasses for a broader view of immune response
• Results grouped by low, moderate, and high reactivity
• Easy-to-use bloodspot collection kit (no lab draw required)
