What does the Vegetarian Food Reactivity Profile test measure?

Why is Vegetarian Food Reactivity Profile measured?

The reactivity profile provides a broad screen of the vegetarian food universe and is used to guide elimination diets or rotation protocols in functional and integrative practice. Because it tests antibodies that reflect exposure as well as potential reactivity, the profile must be interpreted with caution — high reactivity to a staple food may simply mean it is eaten regularly. Clinical correlation with symptoms, and empirical elimination-rechallenge, remain the gold standard for confirming food intolerance.

Reference ranges

Standard reference

Foods are classified as negative, borderline, or elevated (moderate/high) for each antibody class; the panel reports reactivity across 198 vegetarian foods.

Functional medicine optimal

Optimal is a low-reactivity profile (most foods negative or borderline), though this is functional-medicine interpretation rather than an evidence-based clinical threshold.

Units

Qualitative classification

Reference ranges vary by laboratory and assay platform. Interpret in context of the issuing laboratory's stated range.
