Skin testing has its: place. Some folks find a food sensitivity test by Great Plains Lab in KS to yield lots of helpful information beyond skin tests. Peace and good health. Wheat and dairy are common allergens.

Fairly Accurate: Negative-predictive accuracy of prick skin testing is high, especially for aeroallergens which are standardized (>95% accuracy). In contrast, most commercially-available food extracts are not standardized. Milk, eggs, peanuts, soy, fish, shellfish, tree nuts are reliable but many fruit and vegetable extracts are not. If negative prick test but concerning history try "pick-by-prick" to fresh food.
