The performance characteristics of the enzyme-linked immunospot assay (ELISPOT) assay (T-SPOT TB) for the diagnosis of latent tuberculosis infection in HIV-infected individuals are unknown. Given that ELISPOT enumerates Mycobacterium tuberculosis antigen-specific IFN-gamma-secreting T cells, HIV-associated immunosuppression might adversely affect test performance. However, we found that 28 out of 29 HIV-positive individuals (97%) gave evaluable test results, and performance was independent of the CD4 T-cell count. ELISPOT test performance appears to be independent of HIV-associated immunosuppression.
