She's a high school athlete with no asthma symptoms post 9 years old? A state board certified pulmonologist examined and cleared her following the chest xray and pulmonary function test. The concern was that there may be an allergic reaction to cat dander. Experienced wheezing and labored breathing after 7th round of the 10 round MCCT. Unfortunately, just getting over a cold and was offered the opportunity to return for a retest (additional fee, of course). Is MCCT failure a final nail and/or should we opt for the retest? Didn't want to dash hopes until all options were exhausted. Thank you in advance.
