Legitimate Food Sensitivity Testing Options
This is a great question because many food sensitivity tests ARE misleading, so it's worth being careful.
Most Reliable Options:
For true IgE-mediated food allergies (the gold standard):
- Quest Diagnostics or LabCorp – blood panels ordered through your doctor for specific IgE allergens
- Skin prick testing through an allergist – considered the most accurate method
For clinical food intolerance investigation:
- Cyrex Laboratories Array 10 – more comprehensive and used by functional medicine doctors, though expensive (~$500+)
- LEAP MRT test – measures inflammatory responses, used by registered dietitians for elimination diet guidance
Be Skeptical Of:
- Everlywell food sensitivity tests – measure IgG antibodies, which most allergists say just indicate food exposure, not problems
- Most mail-order IgG tests – not validated by mainstream medicine
- Hair analysis tests – no scientific basis
Honest Recommendation:
The most effective approach is working with an allergist or gastroenterologist who can order proper testing AND guide an elimination diet, which remains the most validated method for identifying food sensitivities.
