<<Disclaimer: Verify this information before applying it to your situation.>> First, let me apologize for to incorrect calculation of number of affected persons in the US. I got the decimal in the wrong place. It was estimated using the number 1 in 150 positive X 280 million population. Should be 1.8 million, rather than 18 million. The responses were from one extreme to the other: 33% pointed out an error in number of persons with CD. 17% said that nothing in the article was correct or useful. 50% said that it was interesting good, or encouraged further thought on Public Health Depts performing screening test. I think what has been done with testing / labeling for persons with phenylketonuria may serve as a model for how we can go to work something out for celiac. Thanks for you responses. Noel
