Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The study compares the biochemical markers in bronchoalveolar lavage samples from asthmatic children to those markers found in non-asthmatic children with other respiratory diseases. The investigators hypothesize that certain markers will be associated specifically with asthma.
