No matter what you do, she will still have the disqualification. I would wait and see what the outcome from the waiver authorities is. If your daughter has not done this, I would have her write a letter detailing exactly what occurred with her asthma, the date that she last took medication, how the asthma has affected her, how she is currently, and what activities she currently participates in. Send this letter to DoDMERB and they will forward it to the waiver authority.
If a waiver is denied, then you can start looking at getting additional testing, but if it hasn't been requested at this point in time I would not do it.
