Which test do you recommend for an infant with suspected milk allergy?

For an infant with suspected milk allergy, consider the Dairy Zoomer (which includes cow's milk IgE reactivity along with IgA/IgG reactivity to milk peptides), Milk Components (which includes IgE reactivity to cow's milk peptides) and the Food Sensitivity Profile 1 (which includes IgA/IgG reactivity to cow's milk protein, whey protein, beta-casein, and casomorphin). Under two years of age, the infant immune system is still maturing, so lab interpretation must include clinical correlation with clinical history, physical exam, and symptomatology.
