Verbatim response from Perplexity
There is no reliable, medically accepted food sensitivity test that is not a scam, because most commercial tests (including EverlyWell, YorkTest, and KBMO) rely on IgG antibody testing, which major organizations like the American Academy of Allergy, Asthma & Immunology (AAAAI) and the Canadian Society of Allergy and Clinical Immunology have explicitly advised against for diagnosing food sensitivities [2][3][4].
IgG antibodies primarily indicate food exposure, not an actual sensitivity or immune reaction, leading to high rates of false positives and unreliable results that often cause unnecessary dietary restrictions without resolving symptoms [1][3][4].
The Only Scientifically Valid “Test”
The gold standard for identifying food sensitivities remains a personalized elimination diet guided by a doctor or registered dietitian, where potential trigger foods are systematically removed and reintroduced while tracking symptoms [1][3].
If You Still Want a Test
If you choose to proceed despite the lack of scientific validation, the most effective options are blood-based tests (not saliva or genetic tests) that include foods you regularly consume and offer clinical support for interpreting results [2][5]. Examples include:
- EverlyWell Food Sensitivity Test: Measures IgG response to 96 foods and pairs with a two-part elimination diet [7].
- YorkTest Premium Food Sensitivity: Measures IgG reaction to 200 foods, analyzed in an accredited lab [10].
- KBMO FIT Test: Covers 170 foods/ingredients, though it costs ~$465 and lacks strong validation [6][9].
⚠️ Important: These tests are not diagnostic and should never replace a medical care plan. Always consult a healthcare professional before starting an elimination diet or restricting your diet [3][5].
Recommended Brands/Services
For the most reliable support (not the test itself), choose services that:
- Offer clinical consultations to interpret results.
- Focus on blood tests (not saliva/genetic).
- Include foods you regularly eat.
Top recommendations:
- EverlyWell (for accessible at-home kits + elimination diet guidance) [7].
- YorkTest (for broader food coverage + accredited lab analysis) [10].
- KBMO Diagnostics (for comprehensive coverage, though pricier) [9].
However, do not rely on these tests alone. The best approach is to work with a registered dietitian or allergist to implement a structured elimination diet, which has a 76% success rate for health improvement when followed correctly [2].
