that the dhea levels that are acceptable for a SWCAH child would be higher than the ones acceptable for a non-cah child.  

I come to that conclusion after finding that they aim for higher levels of 17 OHP in SWCAH or CAH. Normal in non-cah where 17 OHP is concerned is supposed to be lower than the recommended ranges in CAH of 10-50nmol/L.  If they aimed for what is normal in non-cah children, then they would end up over treating.  It is natural to therefore assume that if the 17 OHP levels are elevated about normal in CAH children that the dhea levels that are taken at the same time as the 17 OHP would be higher also.  So possibly those levels given may not be accurate. 

From what I understand. Once they manage to control the 17 OHP within the middle to top end of those ranges--say 20nmol/L to 40nmol/L,  this is when you will achieve the normal ranges in DHEA’s also.  If you go below 10nmol/L I would imagine that you would completely suppress the DHEA levels and other hormones after 17 OHP, and therefore also growth. 

I was trying to look what normal is myself so posted.
