In our study we show that pre-incubation of lymphocytes with PPD "in vitro", produces a significant increase in the number of E active rosettes. This increase is only for subjects with cutaneous hypersensitivity to tuberculin. We think this is a specific test and we studied the confidence interval for our results. We discuss the possibility to evaluate the immune-status of a subject, testing his lymphocytes with a panel of antigens. The active E rosette test is simpler, cheaper and easier to perform than other tests to evaluate the cellular immune-status of patients.
