I did the Alcat. I eliminated the foods I showed intolerance to. Saw immediate results. Testing was easy to order on the web. Found best pricing at foodallergytest.org (Even better pricing than ordering direct from Alcat!) Got the blood drawn at a local clinic with no problem.
This was several years ago that I did the Alcat. I now eat most of the offending foods - in moderation- without a reaction. It is great to again have a vaired diet (and is much healthier that having a restricted diet!) It is also great not to be afraid of food!
