Prognostic Value of a T-Cell–Based, Interferon-γ Biomarker in Children with Tuberculosis Contact

Abstract
Identifying people at high risk for active tuberculosis after exposure to infected persons is important. Information about the ability of interferon-γ–release assays, such as enzyme-linked immunosp... Background: Enzyme-linked immunospot (ELISpot) assay is an increasingly widely used, T-cell–based, interferon-γ–release assay for diagnosing tuberculosis infection, but whether positive results are...
