Your story somewhat sounds like mine, first of all where in Tx do you live in? My sons first level were in the 10, 000 and was put on meds and his ednro also thought he might not have CAH.  After repeating his test, I felt it was best if we would do the genetic testing because his endro couldn’t figure it out.  My son who is 14mth was recently diagnosed thankfully with the help of the genetic testing.  I also like in tx and we are considering finding another endro due to his busy schedule.
