Needed: Volunteers with positive TB tests

Volunteers with positive tests for TB are needed for studies of protective immunity against tuberculosis.

We can accept positive results from TB skin tests (aka “PPD” or “tuberculin” tests) or TB blood tests.

Volunteers must be non-smokers who do not have asthma or other chronic lung disorders or recipients of the TB vaccine BCG.

Healthy non-smokers who have not had positive TB tests can be also included as control subjects.

Volunteers will be financially compensated.
