Skin Test Reactivity and Cellular Immune Responses to Mycobacterium avium Sensitin in AIDS Patients at Risk for Disseminated M. avium Infection

Skin tests and lymphocyte proliferation assays (LPA) were performed with Mycobacterium avium sensitin on patients with AIDS. Among 139 subjects, 13% had positive skin test results and 32% had positive LPA results. The LPA may be a more sensitive indicator of prior M. avium infection in this population.
