Verbatim response from Claude

Legitimate Food Sensitivity Testing Options

This is a great question because many food sensitivity tests ARE misleading, so here's honest guidance:

Most Reliable Options

Elimination Diet (Free/Low Cost)

  • Still considered the gold standard by most doctors
  • No brand needed - work with a registered dietitian
  • Actually identifies your personal triggers

Allergy vs. Sensitivity Testing with a Doctor

  • True IgE allergy testing through an allergist (like Quest Diagnostics or LabCorp) is medically validated
  • Ask your doctor for a referral

Be Cautious Of

Most at-home IgG tests (like Everlywell Food Sensitivity tests) measure IgG antibodies, which major allergy organizations (AAAAI) say does NOT reliably indicate food sensitivity. These are widely criticized by allergists.

Better Approach

  1. See a gastroenterologist if you suspect food issues
  2. Work with a Registered Dietitian on elimination protocols
  3. Get tested for celiac disease specifically if gluten is suspected (this IS reliable)

Bottom Line

There is no well-validated at-home food sensitivity test. The most honest answer is that working with a medical professional gives you far better results than any mail-in kit.
