The short answer: no, not reliably. While some genetic variants (e.g., in HLA or lactase genes) influence certain food reactions, IgG testing for 'delayed intolerances' lacks robust clinical evidence. Most IgG tests marketed directly to consumers are not validated for diagnosis; they often produce false positives and lead to overly restrictive diets. The few well-established genetic intolerances (lactose, gluten) are diagnosed via specific tests, not IgG panels. Therefore, basing dietary decisions on a DTC DNA test for IgG intolerance is not supported by current science.

Lifestyle factors (sun exposure, diet, skin type) and latitude dominate. A DNA test alone cannot reliably predict deficiency or guide personalized supplementation. Clinical guidelines recommend measuring serum 25(OH)D rather than genetic markers.
