yes, we just did the regular scratch testing. We centered it on foods, since that was my primary problem. We got a lot of them, then tested for environmental things later. Over the years, we have figured things out by process of elimination. (i.e. I am not allegic to cats, but had a reaction one time petting a friends cat. Turns out it was an indoor/outdoor cat, so I was probably reacting to the grass pollen on the cat's coat. I personally avoid beef altogether, and onl eat organic poultry and fresh caught seafood (I live close to the ocean so it is not a problem). It was also drilled into me as a child to never eat anything if I could not identify the ingredients (to this day I still won't eat a casserole).
I actually went through allergy shots for the environmental allergens that could not be avoided. I know some people really hate the concept of allergy shots, but our goal was to get my eczema under control and to not have to take allergy meds every day for the rest of my life. It worked, I my eczema is clear most of the time, I am off inhalers, and I only have to take benadryl when I need it. I also had a wonderful allergist from south africa who understood that the goal was first control and comfort, and eventually to be able to maintain that off daily medication.
