My son has allergies and was diagnosed with asthma when he was younger. According to his doctor Looks like last medication documented for asthma was 12/11/13--that was both an inhaled steroid and rescue inhaler... Not necessarily prescribed but documented that he has at one time in his history used those medications... That was a couple of months after his 13th birthday. However he does take singulair to help with his allergies (dust/mold). This medication can also be used for asthma. His overall fitness is excellent. How concerned should we be? Should we proactively get a spirometry test so that would be in his records? Anybody know the target score for that test? Thanks!
