Plasma samples from 200 N‐TB patients, 102 R‐TB patients, and 102 controls were subjected to both quantitative RT polymerase chain reaction (RT‐qPCR) and enzyme‐linked immunosorbent assay to determine plasma levels of CCAT1, IFN‐γ, IL‐1β, iNOS, TNF‐α, and IL‐10. This evidence concerns the gene TNF and tuberculosis.
