Summary

The purpose of this research study is to collect lung tissue and fluid from two groups of people: those who have severe asthma, and those who do not. These samples will then be tested in a laboratory to identify differences in the lung tissue cells and fluids that may exist between these two groups of people.

Conditions

• Severe Persistent Asthma

Interventions
