Sensitivity limits: Most consumer tests detect gluten above 10-20 ppm (parts per million). The FDA gluten-free standard is under 20 ppm.

Celiac Safety Glossary
- Gluten
- Gluten is a family of storage proteins (prolamins and glutelins) found naturally in cereal grains like wheat (including varieties like spelt, kamut, and farro), barley, and rye, which acts as a binder to give food elasticity and shape.
- Cross-contamination
- Cross-contamination (or cross-contact) occurs when gluten-free food comes into contact with gluten-containing food or surfaces β such as shared cutting boards, toasters, fryers, or utensils β rendering otherwise safe food dangerous for people with celiac disease.
- Parts Per Million (ppm)
- Parts per million (ppm) is a unit of measurement used to quantify gluten concentration. Labeling laws in the US and Europe permit a maximum threshold of 20 ppm, while Australia requires no detectable gluten (0 ppm).
