Hence, studies using these biomarkers ideally require confirmation of allergy with double-blind, placebo-controlled food challenge trials.
In some cases, the use of skin prick tests and double-blind placebo-controlled food challenge were felt to be inappropriate because of ethical concerns in the use of normal volunteers for the purposes of safety assessment.
Skin prick testing to food allergens (17-19,22) or IgE levels specific to food allergens (21), as an indicator for food allergen sensitisation were performed in five of these trials, however food challenges to confirm the diagnosis of food allergy were only done in two studies (18,19), with only one using double-blind, placebo-controlled food challenges (18).
