Oxidative stress is seen in children with asthma, but is hard to measure. The investigators
exploring the utility of using a commercially available assay to measure oxidative stress in
the urine in asthmatics. Additionally, the investigators will attempt to prove that
oxidative stress is higher in children with acute asthma compared to those with stable
asthma and that this stress is also higher in children with more severe clinical asthma
exacerbations compared to less severe ones.
