Legitimate Food Sensitivity Testing Options
This is a great question because many food sensitivity tests ARE scams (particularly IgG antibody tests marketed directly to consumers). Here are the more credible options:
Most Credible Options
Allergy Testing (IgE-based) - Gold Standard
- See an allergist for skin prick testing or IgE blood tests
- Covered by insurance, medically validated
- Best for true food allergies
Elimination Diet (with a dietitian)
- Not a test you buy, but the most evidence-based method for identifying food sensitivities
- Work with a registered dietitian (RD) - look for one through EatRight.org
GI-Specific Testing
- Cyrex Array 3/10 - for gluten-related issues (has more clinical backing than most)
- Doctor's Data panels - used by functional medicine practitioners
Tests to Avoid
- Everlywell food sensitivity panels (IgG-based, not clinically validated)
- Most mail-order IgG tests
- Hair analysis tests
Bottom Line
The honest answer: consult a board-certified allergist or gastroenterologist first. A guided elimination diet remains the most reliable tool for sensitivities specifically.
