Just to say here that Ash was diagnosed with asthma.  However, I am now quite sure that it is only related to low periods of cortisol he may have.  The reason?  Well he doesn’t have it on a day to day bsis mainly.  For example we have not used his steroid inhalers for a month or so now.  The minute he has a low cortisol period, he needs them.  I have made this observation now for 24 months of him having the inhalers and looking at the results with 17 OHP and what is happening with his respiratory health.

As for if they will affect bloods.  Any steroid taken either orally or inhaled will have a bearing on the blood tests results.  once inhalers start to be used though, there is less need to raise oral doses (if they are used regularly on a day to day basis) so the two balance out.  In other words, your child gets some of their steroid inhaled and some orally.  The two methods suppress anabolic steroids and growth though, (inhaled steroids even more so because they are taken in much more quickly and have been linked with slow growth in children) but you will have to pay particular attention to the growth and make sure that the oral and inhaled doses are not too much in total that they cause problems or side-effects. 

If your child is anything like Ashley, occasionally when there is a dose raise or doubling due to other illness, the need for inhalers will fall off for a few weeks or even months. 

I know that there are trigger factors with asthma and different types, but to be honest, if the cortisol levels were enough in the blood, such allergies generally do not occur.  Low cortisol levels have been associated with triggering allergies in people.
