Do some do the anti MAP if they tested neg. for CMV

You should test first for MAP before considering triple antibiotic therapy. Or at least I think this would be a good approach.

pzm diagnostics is a new place in the US - www.crohnsmanagement.com

There is also a lab in the UK and and New Zealand but at the moment I am unaware of their links or contact information. But others on here may know and hopefully could post contact information.
