Verbatim response from Perplexity
There is no reliable at-home “food sensitivity” test that can legitimately tell you which foods are causing chronic symptoms; the most evidence-based approach is to identify the specific problem first and use validated testing for food allergy or celiac disease, or a supervised elimination-and-rechallenge for suspected intolerance/sensitivity.[2][6][7][10]
If you want the least scam-like answer, it is not an IgG food sensitivity panel such as Everlywell or similar direct-to-consumer tests, because major allergy organizations say IgG food tests have not been scientifically proven to diagnose food sensitivity and can produce misleading results.[1][6][10] Reviews that rank Everlywell “best overall” are evaluating convenience and packaging, not scientific validity.[1][4]
What to do instead:
- If you get immediate symptoms like hives, swelling, wheeze, or vomiting, ask a clinician/allergist about a food allergy test such as skin-prick testing or specific IgE blood testing.[3][10]
- If you suspect celiac disease, get proper celiac testing through a clinician before removing gluten.[2]
- If symptoms are delayed and nonspecific, use a food and symptom journal plus a structured elimination diet and reintroduction with medical or dietitian guidance.[2][7][10]
If you still want a consumer product anyway, I would not call any of them scientifically solid; the best-known brands like Everlywell, YorkTest, and similar IgG panels are the ones most often criticized by allergy societies.[1][6][10]
