Legitimate Food Sensitivity Testing Options
This is a great question because many food sensitivity tests ARE scams, so it's worth being careful.
Most Reliable Options:
1. Allergist/Doctor-Ordered Tests (Best Option)
- See an allergist for skin prick tests or IgE blood tests (like ImmunoCAP by Thermo Fisher)
- These test for true food allergies, which are well-validated
- Covered by insurance in many cases
2. Elimination Diet (Gold Standard for Sensitivities)
- Not a product, but the most scientifically supported method
- Often guided by a registered dietitian
- Services like working with a dietitian through Nourish (telehealth) can help structure this
3. If You Want a Blood Test Specifically
- Cyrex Laboratories Array 10 is considered more credible than most consumer options
- Should be interpreted by a functional medicine doctor
What to Avoid:
- Everlywell food sensitivity tests - IgG testing is not considered clinically valid by most allergists
- Hair analysis tests
- Most direct-to-consumer IgG panels
Bottom Line:
See an allergist + try an elimination diet with a dietitian. That combination is the most evidence-based approach available.
