LabCorp has a large IgG food panel. Patient brought the results in and the lab picked up a lot. What do you think about that?

Chris Kresser:  I don’t have a lot of confidence in it. Back when we talked about the Cyrex arrays, I mentioned several advantages that their testing has over typical IgG testing, and I’m not confident that LabCorp is going to the lengths that Cyrex is going to to ensure that the samples are valid and they are double-checking each sample when they coming in and they’re using the proper antigens, etc., so I would be somewhat skeptical. Even with Cyrex, as I mentioned, I suggest checking it out with elimination and provocation. I just think we still have a lot to learn in that department.
