Logan hasn't had any lab test done. We started him on the GFCF diet after I read the book "Unraveling the Mystery of Autism" by Karyn Seroussi. From there we found a place that uses the BioEnergetic Stress Test (along with other lab testing) and have gone there to test Logan's sensativates(sp). Because of our money situation, that's as far as we've gone with his testing. Have you heard, or tried this type of testing?
