Normal Control Cohort Sample Bank

Completed

Conditions studied: Healthy

In brief

This study is designed to collect lung washing samples and small pieces of tissue (biopsies) from the lungs of people who do not have any allergies or asthma. These samples will be used by researchers in the future as control samples to compare to samples from people with chronic lung diseases such as allergic asthma or emphysema. Control samples are samples are very important in laboratory experiments so that the researchers can tell what may be labeled as different or abnormal in samples from people with lung disease.
