   I would like to start gathering infomation on dna testing for my son.  He
has some symptioms but biopsy after a short challenge and blood test have
been negative.  Maybe someone who does dna testing could help me with a few
questions.  Wouldn't it be better to find out before he has full blown sprue
rather than after?  Is dna testing to expensive and to complicated to do just
to satisfy my worry about my son?

   Any help or web pages with information will be appreciated.
