Legitimate Food Sensitivity Testing Options
This is a great question because many food sensitivity tests ARE scams, particularly IgG blood tests marketed directly to consumers.
What Actually Works:
1. Elimination Diet (Gold Standard - Free)
- Not a product, but the most scientifically validated method
- Work with a registered dietitian for best results
- Services like Zoe can help guide the process with gut microbiome data
2. Medically Supervised Allergy Testing
- Quest Diagnostics or LabCorp through your doctor
- IgE testing for true allergies is legitimate
- Skin prick tests ordered by an allergist
3. For Celiac Disease Specifically
- Everlywell Celiac Disease Screening Test - measures legitimate markers (tTG-IgA)
- Better confirmed through your doctor
What to Avoid:
- Everlywell Food Sensitivity Test (IgG-based) - not clinically validated
- Viome food sensitivity claims - overstated
- Hair sample tests - complete pseudoscience
- Most mail-order IgG panels
Best Practical Recommendation:
See a board-certified allergist or gastroenterologist and ask for proper testing based on your specific symptoms.
