I had genetic testing to see if we (my husband and myself) and my unborn child had or would have CAH. I was told my doctors that the "best" and maybe the only testing site was at the Laboratory of Pediatric Endocrinology at New York - cornell Medical Center. The email is acarso@mail.med.cornell.edu The telephone is Ann Carlson, MS, Genetic Counselor at 212-746-3495. web page - http://pedsendo.med.cornell.edu/cah/factshet.htm Anyway they took blood samples from my husband, our first child, and me. Then while pregnant I was genetic testing - CVS done at 10 week (tested the unborn baby) because our older child had CAH. My husband and I are carriers. I agree with the above post - if you are not a carrier or have CAH - it does take two recessive genes, therefore you don't need to worry or have. preston@kreative.net
