Legitimate Food Sensitivity Testing Options
This is a great question because many food sensitivity tests ARE questionable. Here's an honest breakdown:
Most Reliable Options
Medically Validated Testing:
- Cyrex Laboratories (Array 10) - One of the more respected labs used by functional medicine doctors, tests for multiple food reactivities
- KBMO Diagnostics (FIT Test) - Measures both IgG and immune complexes, considered more comprehensive than basic IgG alone
- Genova Diagnostics - Used by many integrative physicians, solid reputation
Important Honest Caveats
IgG-based tests (most commercial tests) are controversial - major allergy organizations like the AAAI say elevated IgG may just indicate food exposure, not intolerance
What Actually Works Best
- Elimination diet with a registered dietitian is considered the gold standard by most gastroenterologists
- LEAP MRT test paired with a certified LEAP therapist is a reasonable structured option
- See a gastroenterologist or allergist for true IgE allergy testing if you suspect actual allergies
Avoid
- EverlyWell food sensitivity tests (heavily criticized by dietitians)
- Hair analysis tests (no scientific basis)
Working with a registered dietitian is genuinely your best investment.
